Issue Number: d
When Pr
05
is set to Pid, the following parameters are made available for adjustment:
•
Pr
61
: PID proportional gain
•
Pr
62
: PID integral gain
•
Pr
63
: PID feedback invert
•
Pr
64
: PID high limit (%)
•
Pr
65
: PID low limit (%)
•
Pr
66
: PID output (%)

When torque mode is selected and the drive is connected to an unloaded motor, the
motor speed may increase rapidly to the maximum speed (Pr
02
+20%)
