6.2 Settings for Emergency Stop
6.2 Settings for Emergency Stop
Emergency stop in this section refers to the following states.
[1] Emergency stop was input (including other axis alarms)
[2] NC power down was detected
[3] A drive unit alarm was detected
6.2.1 Deceleration Control
(1) Setting the deceleration control time constant
Set the time for stopping from the maximum motor speed (TSP) in the deceleration time constant for emergency
stop (SV056: EMGt). When "0" is set, the deceleration stop is executed with "7000ms".
<Operation>
When an emergency stop occurs, the motor will decelerate at the same inclination from each speed.
(Note) If the setting value of SP056 is longer than the value of SP055, the motor will coast.
【#13055】 SP055 EMGx Max. gate off delay time after emergency stop
Set the time required to forcibly execute READY OFF after the emergency stop is input.
Normally set to "20000".
When "0" is set, READY OFF is forcibly executed with "7000ms".
When the set time is shorter than the time to decelerate and stop, the spindle will stop with the
dynamic brake after the set time is out.
---Setting range---
0 to 29900 (ms)
【#13056】 SP056 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 the maximum motor speed (TSP).
When "0" is set, the deceleration control is executed with "7000ms".

0 to 29900 (ms)
