Installation/Wiring

2–27

Available Functions for Inputs 3 through 8

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

Important:

If a Control Interface Option is not installed, the [Input
Mode] parameter must be set to “Status” (default) and
jumpers must be installed as shown in

Figure 2.7

. If the

drive was shipped from the factory without the option,
these jumpers will have been installed.

Important:

The [Input Mode] parameter can be changed at any time,
but the change will not affect drive operation until power
to the drive has been removed and bus voltage has decayed
completely. When changing this parameter, it is important
to note that the functions of the Start and Stop inputs will
change when power is reapplied to the drive.

Decel

Closing these inputs will command the corresponding accel or decel rate. If both inputs are open or both
are closed, the current rate is maintained.

Accel/Decel

Allows selection of the accel or decel time used by the drive. 1=2nd, 0=1st

Auxiliary

Faults 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.

Clear Fault

If drive has faulted, closing this input will clear the fault.

Digital Pot (MOP) Up/
Down

These inputs increase (up) or decrease (down) the drive commanded frequency when MOP (Motor Oper-
ated Potentiometer) is chosen as the frequency command source. The rate of increase/decrease is pro-
grammable.

Forward

Closing these inputs (Forward or Reverse) commands the corresponding direction. If both inputs are open
or both are closed, the current direction is maintained.

Jog

Closing this input starts the drive and causes it to run at programmed jog frequency. Opening this input
stops the drive using 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.

Rev/For

Available only with three-wire control - Closing this input commands reverse direction and opening this
input commands forward direction.

Reverse

See “Forward” above.

PI Enable

Enables the output of the process PI loop.

PI Reset

Opening this input clamps the process PI integrator value at zero. Closing this input allows the integrator
to continue to operate.

Run Reverse

Available Only with two-wire control - Closing this input issues both a start command and a reverse com-
mand to the drive. Opening the input 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.

Stop Type

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

Sync

Normally wired to multiple drives – When the Sync input is low, the drive operates normally. When the
input is high, the speed of the drive will be held constant and the speed command will have no effect. Dur-
ing this period the speed input of the drive will normally be changed to a different source and/or value.
Allows synchronized change of frequency command to multiple drives.

Traverse

Setting this input low disables the traverse function. When the input is high, the traverse function will be
active. [Speed Control] must also be set to “P Jump” for the function to be active.
