VGCCR (#1) 1: To enable the current loop 1/2 PI control function for cutting only
(This function is used together with the cutting feed/rapid traverse
velocity loop gain switch function.)
<3> To enable the function at all times while using bit 1 of parameter
No. 1742 (Series 15i) or No. 2202 (Series 16i and so on), use the
following bit in addition to the settings of <1> and <2>:
#7 #6 #5 #4 #3 #2 #1 #0
1742 (FS15i)
PIAL
2202 (FS30i, 16i)
PIAL (#2) 1: To enable the current loop 1/2 PI control function at all times
(When this function is used together with the cutting feed/rapid
traverse velocity loop gain switch function)
CAUTION
If the motor activation sound or vibration in the stop
state increases when this parameter is set, turn off
this parameter (do not use this parameter).
(5) Current control PI rate modification
The current control PI rate (p in Fig. 4.5.5) is usually fixed at 1/2, but
can be changed freely.
* This function cannot be used with Series 9096.
2736 (FS15i)
Current control PI rate
2323 (FS30i, 16i)
[Valid data range] 0 to 4096
[Unit of data] 4096 represents p = 1.0 (complete PI).
When the value 0 is specified, the specification of 2048 (1/2PI), which
is equivalent to p = 0.5, is assumed.
CAUTION
If you need to increase the velocity gain, in
particular, a value greater than 1/2PI may be set.
However, do not use this parameter usually.
