Chapter 4 Explanation of Functions

4.2.6 Stop mode selection

b091: Stop mode selection
F003/F203/F303:

Deceleration (1) time setting,
1st/2nd/3rd motors

b003: Retry wait time before motor restart
b007: Restart frequency threshold
b008: Restart mode after FRS

Related code

The stop mode selection function allows you to select one of
two methods of stopping the motor when a stop command is
input from the digital operator or via the control circuit terminal
block. One is to decelerate the motor according to the specified
deceleration time and then stop it; the other is to let the motor
run freely until it stops.
If a start command is input while the motor is in free-running status, the inverter will restart the motor
according to the setting of the restart mode after FRS (b088). (See Section 4.2.47.)

4.2.7 STOP key enable

b087: STOP key enable

Related code

When the control circuit terminal block is selected as the device to input
operation commands, the STOP key enable function allows you to enable
or disable the motor-stopping and trip reset functions of the STOP key of
the digital operator.
This function is effective only when the digital operator (02) is not specified for the run command source
setting (A002) (see Section 4.2.5).
If the digital operator (02) is specified for "A002", the motor-stopping and trip reset functions of the STOP
key are enabled regardless of this setting (STOP key enable).
