3 SPECIFICATIONS AND FUNCTIONS

1: Configure up the power supply circuit which switch off the electromagnetic contactor (MC) after detection alarm occurrence on the PLC

2: The power supply for the electromagnetic brake is possible to use a full wave rectified power supply.

3: The forced stop is possible to use a forced stop terminal of the servo amplifier.

4: 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.

5: 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

6: If the emergency stop signal of QD75MH turns OFF when setting of Pr.82 Forced stop valid/invalid setting to "0 : Valid", servomotor is

stopped with dynamic brake. (The LED display of servo amplifier indicates "E7" (Controller forced stop warning).)

7: 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.

8: The status of forced stop input signal can be confirmed with Md.50 Forced stop input.
