3.7.8 Handling of Power Loss
Use the following memory switch to specify whether to output a servo alarm when power
loss occurs.
Cn-01 Bit 5
Operation to Be Performed at
Recovery from Power Loss
Factory
Setting: 0
For Speed/Torque Control
and Position Control
If the SGDB SERVOPACK detects instantaneous
voltage drop in power supply, it can output servo
alarm A.F3 to prevent a hazardous situation. This
memory switch is used to specify whether to out-
put this alarm.
Setting Meaning
0 Does not output a servo alarm after recovery from power loss.
1 Outputs a servo alarm after recovery from power loss.
Normally, set this memory switch to 0. If the /S-RDY signal is not to be used, set the
memory switch to 1. The /S-RDY signal remains OFF while the main power supply is
OFF, regardless of the memory switch setting.
