Caution
You can select whether or not to activate Err13 (Main power under-voltage protection)
function while the main power shutoff continues for the setup of Pr5.09 (Main power-OFF
detection time).
Setup value Action of main power low voltage protection
0
When the main power is shut off during Servo-ON, Err13 will not be triggered and the
driver turns to Servo-OFF. The driver returns to Servo-ON again after the main power
resumption.
1
When the main power is shut off during Servo-ON, the driver will trip due to Err13 (Main
power low voltage protection).
This parameter is invalid when Pr5.09 (Detection time of main power OFF)=1000. Err13 (Main
power under-voltage protection) is triggered when setup of P5.09 is long and P-N voltage of
the main converter falls below the specified value before detecting the main power shutoff,
regardless of the Pr5.08 setup.

* 1 Positional deviation/feedback scale deviation is maintained during alarm condition and will be
cleared when the alarm is cancelled.
* 2 Action of A/B: When an alarm requiring emergency stop occurs, the action A is selected when the
setup value in the table is set within the range 4 to 7, causing emergency stop of operation. When
an alarm not requiring emergency stop occurs, it triggers dynamic braking (DB) specified by action
B, or free-running.
* 3 Deceleration period is the time required for the running motor to speed down to 30 r/min.
