Stop Selection (Pr. 250) - Mitsubishi Electric FR-F740 EC Instruction Manual

Parameter
6.8.3

Stop selection (Pr. 250)

Used to select the stopping method (deceleration to a stop or coasting) when the start signal
turns off. Used to stop the motor with a mechanical brake, etc. together with switching off of the
start signal. You can also select the operations of the start signals (STF/STR). (Refer to section
6.9.4 for start signal selection.)
Pr. Initial
Name
No. Value
250
Stop selection 9999
The above parameter can be set when Pr. 160 = 0.
Set Pr. 250 to "9999" (initial value) or "8888". The motor decelerates to a stop when the start sig-
nal (STF/STR) turns off.
Fig. 6-53:
Use Pr. 250 to set the time from when the start signal turns off until the output is shut off. When
any of "1000" to "1100" is set, the output is shut off after (Pr. 250 − 1000)s.
The output is shut off when the time set in Pr. 250 has elapsed after the start signal had turned
off. The motor coasts to a stop.

Stop Operation
The motor is coasted to a
stop when the preset time
elapses after the start signal
is turned off.
The motor is coasted to a
stop (Pr. 250 − 1000)s after
the start signal is turned off.
When the start signal is
turned off, the motor decel-
erates to stop.
Deceleration starts when start signal turns off
