Forward or Reverse Selection
This feature provides the ability to change the direction of rotation of a motor used in an industrial applica
-
tion. The direction can be set using either the keypad
FWD/REV
button, or by setting the following parameter:
Load Rotation [SET–15]:
Setting this parameter to
FWD & REV
enables the keypad button. Selection of either
FWD Only
or
REV Only
permanently sets the direction and disables the keypad button. This provides protection
to prevent a motor from running in a direction that could damage equipment, such as a pump or fan.
IMPORTANT:
Do not use the Load Rotation setting to correct a motor that is running backwards because of
incorrect wiring.
Jog Feature
The Jog feature provides the ability to activate a motor momentarily. The command can be executed using
either the keypad
F1
button, or switches connected to a digital input.
•
When using the keypad, the motor direction depends on the
Load Rotation [SET–15]
setting. Digital inputs
can be set to either forward or reverse.
•
The jog command cannot be used when the drive is running.
•
When the jog command is active, other run commands are unavailable.
Jog Frequency [VFD–55]:
This sets the speed the motor will run when the jog command is active.
Jog ACC Time [VFD–53]:
This sets the acceleration time from 0 Hz to
[VFD–55]
.
Jog DEC Time [VFD–55]:
This sets the deceleration time from
[VFD–55]
to 0 Hz.
