*1: Valid when (Frequency setting mode selection 1) is set at  (Up/down frequency).
The frequency setting range is between =
~(Upper limit frequency). The acceleration/deceleration time with
respect to the frequency setting remains
/, unless switching between acceleration and deceleration is
performed.
*2: To switch acceleration/deceleration pattern, V/f pattern, torque limit 1~4, give the following signals to switching functions.
Switching signal 1 Switching signal 2
Acceleration/deceleration, V/f, torque limit 1 OFF OFF
Acceleration/deceleration, V/f, torque limit 2 ON OFF
Acceleration/deceleration, V/f, torque limit 3 OFF ON
Acceleration/deceleration, V/f, torque limit 4 ON ON
*3: If , (F: Forward run command) or , (R: Reverse run command) is assigned at the same time, this function
has a priority.
*4: After the motor slows down and comes to a full stop at a pre-excitation command, the motor is set free momentarily to
bring it into a pre-excitation state. This function should not be used when
 is set to or . Or the inverter
might malfunction.
