Output current can be limited within a range of approximately 30% to 150%
(1% step).
Automatic Acceleration and
Operation
Slip Compensation Control
Multi-Step Frequency Setting
Can be used to avoid DC Link overvoltage trips caused by motor
regeneration during deceleration.
Maintains motor at constant speed with load fluctuations.
Seven adjustable frequency presets can be selected via three external
contacts.
Up-Down Control External momentary contacts can be used to control frequency increase
decrease.
Momentary Power Failure Restart
inverter Bypass Logic
Bias Frequency Setting

Setting Signal Characteristics
Upper and Lower Limiters of Output frequency can be limited to a specified range (overiding frequency
Output Frequency reference).
PFiOTECTiON/DETECTiON:
OPERATION:
Frequency Reference Signals
input Signals
Output Signals
After momentary power failure, automatic restart is possible.
Allows switching the motor between the inverter and the power line.
Magnitude of the bias added to the frequency reference signal can be set
from 0 to 100% (1% step).
Up to three resonant frequencies can be skipped. Width adjustable from
0 5 Hertz
step).
Makes bipolar frequency reference input possible. (Reverse motor rotation
by changing frequency reference voltage polarity, rather than by using
REV-CM contact.)
Stall Prevention, Overcurrent, Overvoltage, Undervoltage,
