*1: Valid when (Frequency setting mode selection 1) is set at (Motor operated pot mop setting).

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/deceleration1, V/f 1, torque limit 1	OFF	OFF
Acceleration/deceleration2, V/f 2, torque limit 2	ON	OFF
Acceleration/deceleration3, V/f 3, torque limit 3	OFF	ON
Acceleration/deceleration4, V/f 4, 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.

*5: Do not set the function " Permission of parameter editing" into the parameter ~ (without option) and~. If it is setted, can not reset the setting.
