MAXVOLT 1 (P37) MAXVOLT 2 (P38) MAXVOLT 3 (P39) MAXVOLT 4 (P40)
Indicates the velocity command corresponding to the maximum speed of gears 1, 2, 3 and 4.
There is no need to set this parameter for an axis handled via CAN.
GAINUNIT (P41)
The CNC takes this parameter into account when operating in closed loop (M19).
Defines the units for s.m.p. PROGAIN (P23) and DERGAIN (P24).
This parameter is used when working with the spindle in closed loop.
A value of "1" will be assigned when the analog command corresponding to a following error of 1
degree is very small. This offers greater sensitivity for adjusting s.m.p. PROGAIN (P23) and
DERGAIN (P24)
ACFGAIN (P42)
The CNC takes this parameter into account when operating in closed loop (M19).
Indicates whether or not the value assigned to a.m.p. DERGAIN (P24) is applied onto the variations
of the programmed speed (AC-forward).
Possible values
Integer numbers between 0 mV and 9999 mV.
Default value: 9500 (9.5 V)
Value Meaning
0 millivolts/degree.
1 millivolts/0.01 degree
Default value: 0 (mV/degree)
Value Meaning
NO It is applied on variations of following error (derivative gain).
YES It is applied on the variations of the programmed speed that are due to
acceleration/deceleration (AC-forward).
Default value: YES
ACFGAIN = NO
ACFGAIN = YES
