Our policy is one of continued research and development. We therefore reserve the right to amend, without notice, the specifications given in this document. (2019 - 9261a) © 2020 IMI International s.r.o. en 1.6.601.015 01/21 1. Rated output and speed of a rotary Servo Motor and a direct drive motor; and continuous thrust and maximum speed of a linear Servo Motor are applicable when the servo amplifier, combined with the Servo Motor, is operated within the specified power supply voltage and frequency. 2. Select the most suitable regenerative option for your system with our capacity selection software. 3. Refer to "Regenerative Option" in this guide for the tolerable regenerative power [W] when regenerative option is used. 4. When using the built-in dynamic brake, refer to "MR-J4-_B_(-RJ) Servo Amplifier Instruction Manual", MR-J4-_GF_(RJ) Servo Amplifier Instruction Manual (Motion Mode) or MR-J4W2-_B MR-J4W3-_B MR-J4W2-0303B6 Servo Amplifier Instruction Manual for the permissible load to motor inertia ratio and the permissible load to mass ratio and details. 5. Terminal blocks are excluded. 6. When the servo amplifiers are closely mounted, keep the ambient temperature within 0 °C to 45 °C, or use them with 75% or less of the effective load ratio. 7. The test pulse is a signal for the external circuit to perform self-diagnosis by turning off the signals to the servo amplifier instantaneously at regular intervals. 8. The rated current is 2.9 A when the servo amplifier is used with UL or CSA compliant servo motor. 9. Fully closed loop control is compatible with the servo amplifiers with software version A3 or later. 10. The command communication cycle depends on the controller specifications and the number of axes connected. 11. The value in brackets is applicable when cooling fans (2 units of 92 mm x 92 mm, minimum air flow: 1.0 m 3 /min) are installed, and then [Pr. PA02] is changed. 12. Servo amplifiers without an enclosed regenerative resistor are also available. Refer to "1-Axis Servo Model Designation" in this catalog for details. 13. Use an optional external dynamic brake with the servo amplifier. Without the external dynamic brake, a Servo Motor does not stop immediately at emergency stop and falls in free-run status, causing an accident such as machine collision, etc. Take measures to ensure safety on the entire system when not using the dynamic brake. 14. This function is available with the servo amplifiers with software version A8 or later. 15. This value is applicable for 750 W or smaller servo amplifiers in 200 V class when a 3-phase power supply is used. 16. This function is available with the servo amplifiers with software version B4 or later. 17. One unit of converter. 18. The servo amplifier built-in regenerative resistor is compatible with the maximum torque deceleration when the Servo Motor is used within the rated speed and the recommended load to motor inertia ratio. Contact your local sales office if the operating motor speed or the load to motor inertia ratio exceed the rated speed or the recommended ratio. 19. Reusable regenerative energy is equivalent to the energy generated under the following conditions. For rotary Servo Motor: the energy that is generated when the machine, whose moment of inertia is equivalent to the permissible charging amount, decelerates from the rated speed to a stop. For linear Servo Motor: the energy that is generated when the machine, whose mass is equivalent to the permissible charging amount, decelerates from the maximum speed to a stop. For direct drive motor: the energy that is generated when the machine, whose moment of inertia is equivalent to the permissible charging amount, decelerates from the rated speed to a stop. 20. This value is the moment of inertia when the rotary Servo Motor decelerates from the rated speed to a stop. When two axes are simultaneously decelerated, the permissible charging amount is equivalent to the total moments of inertia of the two axes. Otherwise, the permissible charging amount is equivalent to the moment of inertia of each axis. The value also applies to the direct drive motor. 21. This value is the mass when the linear Servo Motor decelerates from maximum speed to a stop. Mass of primary side (coil) is included. When two axes are simultaneously decelerated, the permissible charging amount is equivalent to the total masses of the two axes. Otherwise, the permissible charging amount is equivalent to the mass of each axis. 22. Not compatible with pulse train interface (A/B/Z-phase differential output type). 23. STO is common for all axes. 24. The load-side encoder and the Servo Motor encoder are compatible only with two-wire type communication method. 25. This value is applicable when a 3-phase power supply is used. 26. Servo amplifier with software version A3 or later is compatible with the command communication cycle of 0.222 ms. However, note that the following functions are not available when 0.222 ms is used: auto tuning (real time, one-touch, and vibration suppression control), adaptive filter II, vibration tough drive, and power monitoring. 27. The value is applicable for the MR-J4-_B-RJ010 servo amplifier only. 28. RS-422 communication is compatible with the servo amplifiers with software version A3 or later. 29. One unit of converter unit is required for each drive unit. Refer to the Users's Manual for the specifications of the converter unit. 30. 0.3 A is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. 31. When using 1-phase 200 V AC to 240 V AC power supply, operate the servo amplifier at 75% or smaller effective load ratio. 32. For the connection example of the power circuit when a DC input is used, refer to the User's Manual. 33. Follow the restrictions in the User's Manual when using the servo amplifiers at altitude exceeding 1000 m and up to 2000 m over sea level. 34. The safety level depends on the setting value of [Pr. PF18 STO diagnosis error detection time] and whether STO input diagnosis by TOFB output is performed or not. For details, refer to the Function column of [Pr. PF18] in the User's Manual. 35. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD07] to [Pr. PD09]. Failure to do so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs. 36. Use the servo amplifier with 75% or less of the effective load ratio when a 1-phase 200 VAC to 240 VAC power supply is used. 37. Refer to relevant Servo Amplifier Instruction Manual for the restrictions when using the servo amplifiers at altitude exceeding 1000 m and up to 2000 m above sea level. 38. MR-J4-_GF-RJ servo amplifiers are available for DC power input. For connection example of power circuit with DC input, refer to relevant Servo Amplifier Instruction Manual. 39. The dynamic brake is electronic. The electronic dynamic brake does not operate when the control circuit power is off. It may not operate depending on alarms and warnings. Refer to "MR-J4W2-_B MR-J4W3-_B MR-J4W2-0303B6 Servo Amplifier Instruction Manual" for details. Amplifier Notes
