4 Setup
228 IB-1501229-F
Set the control time constant in dual feed back.
When the function is valid, the standard setting is "100". When "0" is set, the value is 1 ms.
When the time constant is increased, the operation will get closer to the semi-closed control and the limit of
the position loop gain will be raised.
However, this cannot be used when the spindle slip occurs in machine configuration such as V-belt drive.
Related parameters: SP017/bit1, SP052
---Setting range---
0 to 9999 (ms)
Set the non-sensitive band in the dual feedback control.
Normally set to "0".
Related parameters: SP017/bit1, SP051
---Setting range---
0 to 9999 (1/1000°)
Set the excessive error detection width in non-interpolation mode.
Standard setting value: ODS = Maximum motor speed [r/min] × 6/PGV/2
When set to "0", the excessive error detection will not be performed.
---Setting range---
0 to 32767 (°)
Set the overrun detection width in the full-closed loop control.
When the gap between the motor side encoder and the machine side encoder exceeds the set value, it is
judged as an overrun and "Alarm 43" is detected.
When "-1" is set, if the differential velocity between the motor side encoder and the machine side encoder
exceeds the 30% of the maximum motor speed, it will be judged as overrun and "Alarm 43" will be detected.
When "0" is set, overrun will be detected with 2°.
In the full-closed loop control, normally set this parameter to "360". During V-belt drive, set to "-1".
---Setting range---
-1 to 32767 (°)
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 instanta-
neous 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.
Related parameters: SP056, SP230
---Setting range---
0 to 29900 (ms)
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".
