Allows jog operation to be started and stopped by selecting the
jog mode (connecting terminals JOG and SD) and turning onloff
the start signal (terminals STF,STR). Jog operation may also be
performed by using the parameter unit. For full information on
the operation procedure, see page 38.
Setting of frequency and acceleration/deceleration time
(1) Confirmation of acceleration/deceleration time
setting range and minimum setting increments
Use Pr. 21 "accelerationldeceleration time increments" to
set the accelerationldeceleration time setting range and
minimum setting increments. Before setting the accelera-
tionldeceleration time, the set value must be checked.
Set value "0"
.....................
0 to 3600 seconds
(factory setting) (minimum setting
increments: 0.1 seconds)
Set value "1" ..................... 0 to 360 seconds
(minimum setting
increments: 0.01 seconds)
