5.1 Configuring the Speed Loop Scan Time
The scan time of the speed loop can be configured using parameter P.019 (Speed
Loop Scan Time). The drive must be stopped to modify the value of this parameter.
Note that P.019 applies only to closed loop speed control using actual measured
motor velocity via tachometer or encoder-type devices.
SPD LOOP SCAN TIME (P.019)
Selects the speed
loop scan time for
closed loop
operation. Parameter Range: 0 = 5 msec
1 = 10 msec
Default Setting: 5 msec
Parameter Type: Configurable
OIM Menu Path(s): Additional Parameters
When FEEDBACK SELECT (P.200) is set to armature voltage, the active speed loop
scan time is fixed at 10 msec regardless of the setting of P.019.
When FEEDBACK SELECT is changed from armature voltage to any other setting, the
active speed loop scan time is determined by the parameter setting of P.019.
