Installation/Wiring

Available Inputs
A variety of combinations made up of the following inputs are
available.

Input

Description

1

st

/2

nd

Accel/Decel

These inputs allow selection of the accel or decel time used by
the drive.

Auxiliary

Required for Operation – this input is intended to fault the drive
via external devices (i.e. motor thermoswitch, O.L. relays, etc.).
Opening this contact will fault (F02 – Aux Fault) the drive and
shut the output off, ignoring the programmed stop mode.

Digital Pot Up/Down

These inputs increase (up) or decrease (down) the drive
commanded frequency when MOP (Motor Operated
Potentiometer) is chosen as the frequency command source.
The rate of increase/decrease is programmable.

Enable

Required for Operation – opening this input shuts the drive
output off, ignoring the programmed stop mode.

Local Control

Closing this input gives exclusive control of drive logic to the
inputs at terminal block TB3. No other devices may issue logic
commands (excluding Stop) to the drive.

Reverse

Available Only with three-wire control – In single source
reversing modes, closing this input commands reverse direction
and opening this input commands forward direction.

Run Forward/Reverse

Available Only with two-wire control – Closing these inputs
issues both a start command and a direction command to the
drive. Opening these contacts issues a stop command to the
drive.

Speed Select 1, 2, 3

These inputs choose the frequency command source for the
drive. See following pages for details.

Start

Issues a Start command for the drive to begin acceleration to
commanded frequency.

Stop Type

Closing this input selects the stop mode in [Stop Select 2] as the
method of stopping when a stop command is issued. Opening
this input selects the stop mode in [Stop Select 1] as the method
of stopping.

Stop/Fault Reset

Issues a Stop command for the drive to cease output per the
programmed stop mode. If the drive has faulted, opening this
input resets the fault if [Fault Clear Mode] is enabled.

Sync

This function has one On/Off input that can come from the
Control Interface option (TB3) or from a local bus type 2
command. The parameter [Sync Time] is associated with the
function.

When the Sync input is low (0), the drive operates normally.
However, when the input is high (1), the speed of the drive will be
held constant and the speed command will have no effect.
During this period the speed input of the drive will normally be
changed to a different source and/or value.

Traverse

The Traverse function has one On/Off input that can come from
the Control Interface option (TB3) or from a local bus type 2
command.

Traverse is disabled by setting either the [Traverse Inc] or
[Traverse Dec] parameter to zero or setting [Speed Control] to
something other than “P Jump.“
