6.19.4 Emergency stop
Hξξξ: Emergency stop
Hξξξ
: Emergency DC braking time
β’ 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 G and the FL relay also are activated.
When setting Hξξξ to ξ (emergency DC braking), set also Hξξξ (DC braking rate) and
Hξξξ (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 Default setting
Hξξξ Emergency stop selection
0: Coast stop
1: Slowdown stop
2: Emergency DC braking
0
Hξξξ Emergency DC braking time 0.0 ~ 20.0 [sec] 1.0
Hξξξ
DC braking current 0-100 (%) 50
(Example of terminal assignment): Assigning the trip stop function to the RES terminal
Title Function Adjustment range Setting
Hξξξ Input terminal selection 3 (RES) 0-64
11 (External trip
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 Hξξξ is
set to 2 (emergency DC braking), set the DC braking starting frequency (Hξξξ) 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............................. "GQHH" will blink.
(2) Press the STOP key once again.......... Operation will come to a trip stop in accordance with the setting
of the ξHξξξ parameter.
After this, "G" will be displayed and a failure detection signal
generated (FL relay deactivated).
