*1 The built-in regenerative resistor is used for MR-JET-40_ to MR-JET-300_. (factory-wired). If using a regenerative option, refer to the
following.
*2 Option cables are recommended for encoder cables. For selecting cables, refer to "Cables/connector sets" in the following manual.
Rotary Servo Motor User's Manual (HG-KNS/HG-SNS)
*3 For connecting servo motor power wires, refer to "CONNECTION OF SERVO AMPLIFIER AND ROTARY SERVO MOTOR" in the
following manual.
Rotary Servo Motor User's Manual (HG-KNS/HG-SNS)
*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 the servo motor for an incorrect 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 power supply, connect the power supply to L1 and L3. Leave L2 open.
*8 When connecting a linear servo motor that has a thermal protector, add a contact that interlocks with the thermal protector output of the
linear servo motor.
