Common
AVR function
AVR function selection
AVR motor voltage selection
• Irrespective of the input power, the output voltage is
corrected and maintained at a constant value according
to the motor voltage. (However, output voltage
exceeding the input voltage of the inverter is not
possible.)
• The AVR function can be turned OFF during
deceleration.

2nd Acceleration time setting
2nd Deceleration time setting
2nd accel/decel change method
Acceleration time crosseover frequency
Deceleration time crossover frequency
• The acceleration and deceleration time can be changed
during operation. Use the 2nd acceleration and 2nd
deceleration times when load inertia changes during
operation.
• Change the acceleration and deceleration time with input
terminals or with the crossover frequency setting.
Acceleration/deceleration pattern
Acceleration pattern selection
Deceleration pattern selection
• The characteristics of acceleration and deceleration can be
selected from among "linear" and "S-curve."
• The S-curve permits softer starts and stops than linear
acceleration/deceleration. It is effective in preventing cargo
from tipping.

Setting the restart (mode)
Restart mode
Allowable undervoltage time setting
Retry waiting time setting
• Retry or restart is possible after undervoltage,
overcurrent, and overvoltage protection functions. (If
the fault conditions still persists after the decided
retrials, the drive will stop.)

Electronic thermal characteristics selection
• Level and characteristic setting are available for the built-in
electronic thermal relay to protect motor from overheating.
