*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.
Acceleration/deceleration1, V/f 1, torque limit 1
Acceleration/deceleration2, V/f 2, torque limit 2
Acceleration/deceleration3, V/f 3, torque limit 3
Acceleration/deceleration4, V/f 4, torque limit 4
*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.
*5: Do not set the function " Permission of parameter editing" into the parameter  ~  (without option)
and  ~  . If it is set, cannot reset the setting. 
