200 V Class - Mitsubishi Electric Melservo-Jet MR-JET Series User Manual

200 V class

For 3-phase 200 V AC to 240 V AC power supply
3-phase
200 V AC to 240 V AC
*1 MR-JET-40_ to MR-JET-300_ have a regenerative resistor. (factory-wired). If using a regenerative option, refer to the following.
Page 57 Regenerative option
*2 Option cables are recommended for encoder cables. For selecting cables, refer to the following manual.
Rotary Servo Motor User's Manual (HG-KNS/HG-SNS)
*3 For connecting servo motor power wires, refer to the following manual.

*4 Use the magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of
80 ms or less. The bus voltage may drop depending on the power supply voltage and operation pattern, causing a dynamic brake
deceleration during a forced stop deceleration. If dynamic brake deceleration is not required, delay the time to turn off the magnetic
contactor.
*5 Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
*6 If ALM (Malfunction) output is disabled with a servo parameter, configure a power circuit which switches off a magnetic contactor after
detection of an alarm occurrence on the controller side.
*7 For 1-phase 200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open.
