• Function
These parameters allow you to specify how to stop operation using an external control device when
an external trip occurs. When operation is stopped, the trip and the FL relay also are activated.
When setting to (emergency DC braking), set also (DC braking rate) and
(emergency braking time)
1) External trip stop via terminals
The external trip stop function can be executed via the a-contact. Proceed as follows to assign an
external stopping terminal and select the stopping method:
[Parameter setting]
Title Function Adjustment range
0: Coast stop
Default setting
Emergency stop selection
1: Slowdown stop
2: Emergency DC braking
0
Emergency DC braking time 0.0 ~ 20.0 [sec] 1.0
DC braking current 0-100 (%) 50
(Example of terminal assignment): Assigning the trip stop function to the RES terminal
Title Function Adjustment range Setting value
11 (External trip
Input terminal selection 3 (RES) 0-72
stop)
Note 1: Emergency stopping via the specified terminal is possible, even during panel operation.
Note 2: If DC braking is not needed to bring the motor to a stop under normal conditions, although is
set to 2 (emergency DC braking), set the DC braking starting frequency () at 0.0 Hz.
2) Emergency stopping from the operation panel
Emergency stopping from the operation panel is possible
by pressing the STOP key on the panel twice while the inverter is not in the panel control mode.
(1) Press the STOP key ............................... "" will blink.
(2) Press the STOP
key once again Operation will come to a trip stop in accordance with the setting
of the parameter.
After this, "" will be displayed and a failure detection signal
generated (FL relay deactivated).
