16 Machine Parameters
#13052 SP052 DFBN
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°)
#13053 SP053 ODS
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
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 (°)
#13055 SP055 EMGx
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.
When using the power backup system, set a value which is not exceeded the initial communication timeout
time of NC (5000[ms]).
Related parameters: SP056, SP230
---Setting range---
0 to 29900 (ms)
#13056 SP056 EMGt
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".
Related parameters: SP055, SP230
---Setting range---
0 to 29900 (ms)
(PR) #13057 SP057 GRA1
Set the number of gear teeth on the spindle side when "the gear selection command (control input 4/bit6, 5)"
is set to "00".
---Setting range---
1 to 32767
(PR) #13058 SP058 GRA2
Set the number of gear teeth on the spindle side when "the gear selection command (control input 4/bit6, 5)"
is set to "01".
---Setting range---
1 to 32767
