Appendix 1 Explanation of Parameters
【#13051】 SP051 DFBT Dual feed back control time constant
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.
---Setting range---
0 to 9999 (ms)
【#13052】 SP052 DFBN Dual feedback control non-sensitive band
Set the non-sensitive band in the dual feedback control.
Normally set to "0".
---Setting range---
0 to 9999 (1/1000")
【#13053】 SP053 ODS Excessive error detection width (non-interpolation mode)
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 (°)
【#13054】 SP054 ORE Overrun detection width in closed loop control
Set the overrun detection width in the full-closed loop control.
When the gap between the main side detector and the sub side detector exceeds the set value, it is
judged as an overrun and "Alarm 43" is detected.
When "-1" is set, the alarm detection will not be performed.
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---
-32768 to 32767 (゜)
【#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".
---Setting range---
-29900 to 29900 (ms)
【#13057(PR)】 SP057 GRA1 Spindle side gear ratio 1
Set the number of teeth on the spindle side when "the gear selection command (control input 4/bit6,
5) "is set to "00".
---Setting range---
1 to 32767
