.8.7 Jog operation (JOG signal): Setting "9"

(1) Jog operation using external signals
Jog operation can be
started/stopped by shorting the
jog mode select terminal JOG-
SD and shorting/opening the
start signal terminal 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 (type with
RS-485 communication function).
The JOG signal has precedence over the multi-speed signal. (External)

.8.8 Reset signal: Setting "10"

Used to reset the alarm stop state established when the inverter's protective function is
activated. The reset signal immediately sets the control circuit to the initial (cold) status,
e.g. initializes the electronic overcurrent protection circuit. It shuts off the inverter output
at the same time. During reset, the inverter output is kept shut off. To give this reset
input, short terminals RES-SD for more than 0.1 second. When the shorting time is long,
the operation panel or parameter unit displays the initial screen, which is not a fault.
Operation is enabled after terminals RES-SD are opened.
The reset terminal is used to reset the inverter alarm stop state. If the reset terminal is
shorted, then opened while the inverter is running, the motor may be restarted during
coasting (refer to the timing chart below) and the output may be shut off due to
overcurrent or overvoltage.
Setting either of "1" and "15" in reset selection Pr. 75 allows the accidental input of the
reset signal during operation to be unaccepted.
(For details, refer to page 94.)
