Settings For Emergency Stop; Deceleration Control - Mitsubishi Electric MDS-E Series Instruction Manual

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 "5000".
When 5000ms or more is set for deceleration time constant at emergency stop (SP056), set the
same value as SP056.
When using the power backup system (MDS-D/DH-PFU) and setting the value of this parameter to
5000ms or more, a communication error between NC and drive unit may occur when power restarts
after a instantaneous power interrupt.
It is not a problem so turn the NC power ON again to start up.
When "0" is set, 7000ms is the actual value to be set.
---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".
---Setting range---
0 to 29900 (ms)
