15 Standard Patterns:
4 for general purpose;
4 for fans and pumps;
1 Custom Pattern: defined by parameter settings.
Multi-step speed operation (9 steps max.), S-curve accel/decel,
zero speed control, servo lock, arbitrary torque detection, etc.
Electronic thermal overload relay
Motor coasts to a stop at approximately 200% rated current.
Motor coasts to a stop by blown fuse.
Motor coasts a stop after 60 sec. at 150% of rated output
current.
Motor coasts to a stop if drive DC bus voltage exceeds
400 VDC (230V unit), or 800VDC (460V unit), or 1050VDC
(600V unit).
Motor coasts to a stop if drive DC bus voltage drops to
190 VDC or below (230V unit), 380 VDC or below (460V unit),
546VDC or below (600V unit).
Factory setting provides for motor to coast to a stop after
momentary power failure of more than 15 ms. Can be
reprogrammed to allow continuous operation (ride-through)
during power failure of up to 2 seconds or longer (see Note 2).
