Rated output and rated speed of the servo motor used in combination with the servo amplifier are as indicated when using the power supply voltage and frequency listed.
The output capacity and speed cannot be guaranteed when the power supply voltage is less than specified.
For torque characteristics applied when the servo amplifier is combined with a servo motor, refer to “servo motor torque characteristics” in this catalog.
Install the cooling fan (1.0m
3
/min, approx. M92).
For products without a dynamic brake (MR-J3-MA-ED), special compliance is possible.
It is possible to change the speed in 10V using the parameter No.C12.
When mounting the amplifier closely, keep the ambient temperature within 0 to 45°C (32 to 113°F), or use with the effective load rate of 75% or less.
The power capacity differs according to the number of input/output points in use. Refer to “MR-J3-MA SERVO AMPLIFIER INSTRUCTION MANUAL” for details.
