Selecting the Reverse Rotation-prohibit
This parameter is used to specify whether to enable or disable the reverse
rotation command sent to the Inverter from the control circuit terminals or
Digital Operator. The parameter should be set to “not accept” when the
Inverter is applied to systems that prohibit the reverse rotation of the Inverter.
Selecting the Reverse Rotation-prohibit (n05)
Set Values
5-8
Selecting the Interruption Mode
This parameter is used to specify the interruption mode when the STOP
command is input.
The Inverter either decelerates or coasts to a stop according to the
interruption mode selection.
Selecting the Interruption Mode (n04)
Set Values
Note
1.
The Inverter will decelerate to stop according to the setting in n17 for
deceleration time 1 if any of the n36 through n39 parameters for multi-
function input is not set to 11 for acceleration/deceleration time selection.
If any one of the n36 through n39 multi-function input parameters is set to
acceleration/deceleration time selection, the Inverter will decelerate to
stop according to the selected setting of deceleration time when the STOP
command is input.
2.
If the RUN signal is input again during a deceleration stop, deceleration will
be stopped at the point of the input and acceleration will proceed at that
frequency.
3.
Do not input a RUN signal during a free-running stop if the motor’s rotation
speed is not sufficient slowed. If a RUN signal is input under these
conditions, a main circuit overvoltage (OV) or overcurrent (OC) will be
detected.
To restart a free-running motor, set a speed search command in one of the
multi-function inputs 1 to 4 (n36 to n39), use the speed search to detect the
speed of the free running motor, and then accelerate smoothly.
