SJ100 Inverter

Remote Control Up and Down Functions

The [UP] [DWN] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration time and deceleration time of this function is same as normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate according to these principles:

•Acceleration - When the [UP] contact is turned ON, the output frequency accelerates from the current value. When it is turned OFF, the output frequency maintains its current value at that moment.

•Deceleration - When the [DWN] contact is turned ON, the output frequency deceler- ates from the current value. When it is turned OFF, the output frequency maintains its current value at that moment.

In the graph below, the [UP] and [DWN] terminals activate while the Run command remains ON. The output frequency responds to the [UP] and [DWN] commands.

• This function is not available when [JG] is in use.

•The range of output frequency is 0 Hz to the value

in A_04 (maximum frequency setting).

See I/O specs on page 4–6.

 

•The minimum ON time of [UP] and [DWN] is 50 ms.

•This setting modifies the inverter speed from using F_01 output frequency setting as a starting point.
