TE Series
NOTE: Jog functions may become disabled by Comm port function F068 setting 3.
See section 5.6.11 for details.
CAUTION
Although the Thermal Register tracks all motor current use, continuous usage of the Jog
feature risks thermal motor damage or nuisance tripping.

The Jog Function is another user optional feature and is controlled by
closing the input on TB1 Terminals 6 and 7. If this input is left open, the
TE Series will ignore all Jog settings. Engaging the Jog feature along
with the Start / Run Command provides an output from the SCRs, but
will not continue ramping to full acceleration. This feature can Jog the
motor at either a preset Voltage (F019 – F021) or a preset Current
(F021) depending upon the settings of the Ramp Type from F010, and
can be initiated along with Ramp 1 or Ramp 2 (see Dual Ramp Select,
Section 4.2.5 and 5.6.2.a). It is also sometimes useful to use Jog in
combination with Ramp 2, see section 4.2.5.c.

Factory Setting = 50%
Range = 5 - 100%
Sets the voltage level of the Jog feature and is typically used to
check rotation, alignment, or to slowly move a load into position.
Jogging at a set voltage has no current control so the duration
of the applied voltage must be limited to prevent excessive
motor heating.
Factory Setting = 10 seconds
Range = 1 - 20 seconds
Set to minimize motor heating during a voltage jog. This setting
is the maximum allowable time for jogging the motor using
voltage only.
