How to use the input signals (assigned terminals
RL, RM, RH, STR)
1.5.6
External thermal relay input:
When the external thermal relay or built-in thermal relay
of the motor (thermal relay protector,etc.) is actuated to
protect the motor from overheating, the inverter output
can shutoff and the corresponding alarm signal can be
outputted to hold at the stop status. Even if the thermal
relay contact resets, the motor cannot be restarted
unless the reset terminals RES-SD are shorted for more
than 0.1s and then opened or a power-on reset is made.
The function may therefore be used as an external
emergency stop signal input.
1.5.7
Jog operation (JOG signal):
(1) Jog operation using external signals
Jog operation can be started/stopped by shorting the jog mode select terminals JOG-
SD and shorting/opening the start signal terminals STF or STR-SD. The jog frequency
and jog acceleration/deceleration time are set in Pr. 15 (factory setting 5Hz, variable
between 0 and 120Hz) and Pr. 16 (factory setting 0.5s, variable between 0 and 999s),
respectively, and their settings can be changed from the operation panel or parameter
unit.
The JOG signal has precedence over the multi-speed signal. (External)
