set output frequency for digital input
Base frequency set as required between 0 and 400Hz. Constant torque or variable torque
pattern can be selected.
150%: At 0.5Hz (for advanced magnetic flux vector control)
Manual torque boost
0 to 3600 sec (acceleration and deceleration can be set individually), linear or S-pattern
acceleration/deceleration mode can be selected.
Operation frequency (0 to 120Hz), operation time (0 to 10 sec), voltage (0 to 30%) variable

selected.
Up to 15 speeds can be selected. (Each speed can be selected in the range of 0 to 400Hz.
The operation speed can be changed from the operation panel or parameter unit during
operation.)

can be set individually.)
Input of frequency setting signal 4 to 20mADC (terminal 4) is selected.
Instantaneous shut-off of inverter output (frequency, voltage)
Alarm retained at the activation of protective function is reset.
