Jog Frequency
Program
Frequency
Jog Settings
This parameter sets the output frequency of the ASD during a
Jog
.
Jogging
is
the term used to describe turning on the motor for small increments of time and
is used when precise positioning of motor-driven equipment is required.
The
Jog
function is initiated via the
Terminal Board
or
using
Communications
(see the
Communications
manual-P/N 53840 for additional
information on using
Communications
for
Jogging
).
The
Jog
function can be activated from zero Hz or from any frequency below
the
Jog Run Frequency
setting (Jog can only increase the speed). A
Jog
command will not be recognized when the running frequency is above the
Jog
Run Frequency
setting. The
Jog
command has priority over other
Run
commands and is not limited by the
Upper-Limit
setting of parameter
F012
.
Jog
commands received for the opposite direction of the commanded frequency
will follow the programmed stopping method of
F261
until reaching zero Hz
and will then ramp to the programmed
Jog
Frequency
and direction.
Jog Setup and Execution
To initiate a
Jog Run
from the EOI perform the following:
1.
Set the
Command Mode Selection
(
F003
) to
Panel Keypad
. This setting
places the ASD in the
Auto
mode.
2.
Set the
Frequency Mode Selection
(
F004
) to
Panel Keypad
.
3.
Enable the
Jog
function (
F262
).
4.
Set the
Input Terminal Priority
(
F106
) function to
Enable
to receive
Jog
commands.
5.
Assign the
Jog
Run
setting to any unused discrete input terminal (Select
from
Table 10 on pg. 234
).
6.
Set the
Jog Frequency
at
F260
.
7.
Set up a
Jog
Stop Pattern
at
F261
.
8.
Press the
Run
key and the ASD will output the commanded frequency (as
programmed; not the
Jog
frequency).
9.
Activate the
Jog Run
terminal (from step
5
). The ASD will output the
frequency setting of
F260
(from step
6
).
10. Stop the
Jog
by either providing a
Stop
command or terminating the
Jog
Run
terminal activation. Providing a
Stop
command will terminate the
commanded frequency and the
Jog
function. Terminating the
Jog Run
terminal activation will terminate the
Jog
function only and will resume the
commanded frequency of step
8
.
