Frequency

This parameter⇒sets the output frequency⇒⇒of the ASD during a Jog. Jogging is the term used to describe turning the motor on for small increments of time and is used when precise positioning of motor-driven equipment is required.

The Jog function is initiated via the Control Terminal Strip or using Communications (for further information on using Communications for Jogging see the Communications manual).

To perform a Jog, first set this parameter to the desired Jog frequency. Jog Using the Control Terminal Strip

To initiate a Jog from the Control Terminal Strip perform the following:

1. Assign a discrete input terminal to the Jog function (see Table 6 on page 138).

2. Assign a discrete input terminal to the F (Forward) function (and Reverse if required) (see Table 6 on page 138).

3. Provide a Forward and/or Reverse command from the Control Ter- minal Strip.

4. Place the system in the Remote mode (Local/Remote LED is off).

5. Connect the assigned Jog terminal (from step 1) to CC for the desired Jog duration.

of the Jump Frequency range and continue upward as programmed.
During deceleration, the output frequency of the ASD will hold at the frequency
of the upper level of the Jump Frequency range until the programmed
deceleration⇒ramp reaches the lower⇒level of the Jump ⇒Frequency range. Then,
the output frequency of the ASD will decelerate to the lower level of the Jump
Frequency range and continue downward as programmed.
If overlapping Jump Frequency bandwidths are set up, the system will respond
with one bandwidth setting that includes the total range.
Once set up and enabled, it is on in all control modes.
User-selected frequencies may be jumped to avoid the negative effects of
mechanical resonance.
