1: Configure up the power supply circuit which switch off the electromagnetic contactor (MC) after detection alarm occurrence on the PLC
CPU.
2: The power supply for the electromagnetic brake is possible to use a full wave rectified power supply.
3: When turning off the control power supply of servo amplifier, communication with servo amplifier is not possible from then on.
Example) If turning off the control power supply of servo amplifier L11/L21 in the above figure B , communication with the servo
amplifier of C cannot be performed either. For turning off power supply of certain servo amplifier, turn off the main circuit
power L1/L2/L3, but do not turn off the control power supply L11/L21.
4: When changing servo amplifier, turn off both the main circuit power L1/L2/L3 and the control power supply L11/L21. As communication
between servo amplifier and QD75MH is not possible at this time, stop the machine operation in advance and then change servo
amplifier.
5: The dynamic brake is operated, and servomotor occurs to the free run when EM1 (forced stop) of servo amplifier turn OFF. At the time,
the display shows the servo forced stop warning (E6).
During ordinary operation, do not used forced stop signal to alternate stop and run.
The service life of the servo amplifier may be shortened.
6: If setting servo amplifier to Axis 1, set the rotary axis setting switch of servo amplifier to "0".
Set "Axis2 => 1 for rotary switch", "Axis3 => 2 for rotary switch" and "Axis4 => 3 for rotary switch" respectively.
