6 Spindle Adjustment
330
IB-1501229-F
(3) Adjustment when the load inertia is large
When the load inertia is large and acceleration time is 10s or more, excessive speed deviation alarm (ALM23) may
occur because the time in which deviation between speed command and speed FB, which is the actual spindle
motor rotation speed, exists is prolonged. In this case, increase the time constant (3101 to 3104) during spindle
rotation by S command. When the acceleration time is 10s or less, use the standard value 300 (300ms).
Alarm can be avoided by adjusting excessive speed deviation timer (SP117). However, in this case, alarm detection
will be delayed during constant speed operation.

#13117
】
SP117 SETM Excessive speed deviation timer
Set the time to detect the speed excessive error alarm.
Set the time required to the machine.
The standard setting is "12".
---Setting range---
0 to 60 (s)
【
#3101
】
sp_t 1 Acceleration/deceleration time constant with S command (Gear: 00)
Set the acceleration/deceleration time constant with S command (speed operation mode) when gear
00 is selected. Set the linear acceleration/deceleration time up to limit rotation speed (slimit1). Set
the short time constant that the motor torque at acceleration is always saturated, however, when an
abnormal noise or V-belt slip occurs, increase the time constant.
---Setting range---
0 to 30000 (ms)
