Description
Used to improve speed accuracy
when operating with a load.
Usually changing this setting is not
necessary.
Adjust this parameter under the fol-
lowing circumstances.
• When motor speed is lower than
the frequency reference increase
the set value.
• When motor speed is higher than
the frequency reference decrease
the set value.
In Closed Loop Vector control this
value is the gain for compensating
the slip caused by temperature varia-
tion.
Sets the Slip Compensation delay
time.
Usually changing this setting is not
necessary.
Adjust this parameter under the fol-
lowing circumstances.
• Reduce the setting when Slip
Compensation responsiveness is
low.
• When speed is not stable, increase
the setting.
Sets the slip compensation limit as a
percentage of motor rated slip.
0: Disable
1: Enabled
When the slip compensation during
regeneration function has been acti-
vated and regeneration capacity
increases momentarily, it might be
necessary to use a braking option
(braking resistor, braking resistor
unit or braking unit.)
0: Disabled
1: Enabled. (The motor flux will be
lowered automatically when the
output voltage become saturated.)
