Description
Sets the pull-in current during acceleration as a
percentage of the motor rated current (E5-03).
Set to a high value when more starting torque
is needed.
Sets the time constant for voltage error
compesation. Adjust the value when
• hunting occurs at low speed.
• hunting occurs with sudden load changes.
Increase in steps of 0.1 or disable the
compensation by setting n8-45 to 0.
• oscillations occur ar start. Increase the value
in steps of 0.1.
Sets the ratio between motor and machine
inertia.
0: less than 1:10.
1: between 1:10 to 1:30.
2: between 1:30 to 1:50.
3: higher than 1:50.
Sets the limit for the output voltage.
Adjustment is normally needed only if the
input voltage is below the n8-62 set value. In
this case set n8-62 to the input voltage.
