MDS-E/EH Series Instruction Manual
5 Servo Adjustment
< Operation >
When an emergency stop occurs, the motor will decelerate at the same inclination from each speed.
Emergency stop (EMG)
Servo READY (READY)
Motor brake control output (CN20)
【#2255】 SV055 EMGx Max. gate off delay time after emergency stop
Set the time required between an emergency stop and forced READY OFF.
Set the maximum value "+ 100ms" of the SV056 setting value of the servo drive unit electrified by the
same power supply unit.
When executing the vertical axis drop prevention, the gate off will be delayed for the length of time
set at SV048 even when SV055's is smaller than that of SV048.
---Setting range---
0 to 20000 (ms)
【#2256】 SV056 EMGt Deceleration time constant at emergency stop
Set the time constant used for the deceleration control at emergency stop.
Set the time required to stop from rapid traverse rate (rapid).
The standard setting value is EMGt≤G0tL×0.9.
However, note that the standard setting value differs from the above-mentioned value when the
setting value of "#2003:smgst Acceleration and deceleration modes bit 3-0:Rapid traverse
acceleration/deceleration type" is 8 or F. Refer to Instruction Manual of the drive unit (section
"Deceleration Control") for details.
