Programmable Digital Input (Control terminal block inputs 1 through 5) Functions

The function of the digital inputs

1 through 5 are programmed via the corresponding PC01 [Digital Input 1]

through

PC05 - [Digital Input 5]. The following programming guidelines must be followed:

No two inputs can be programmed for the same function.

The PTC input (setting 19) is only programmable on input terminal 5.

The digital inputs can be programmed to respond to NO (Active High) or NC (Active Open) inputs via
PC11 - [Digital Input 1 Logic] through PC15 - [Digital Input 5 Logic].

ATTENTION

• All digital inputs respond to level sensitive commands.
• Inputs do not require a voltage transition (cycle) after a fault condition is cleared, after input power cycling or after

programming the logic of the digital input.

• All digital inputs can be programmed as NO or NC. HOWEVER, THE

START COMMAND SHOULD BE SET AS NO

(ACTIVE HIGH) AND THE STOP COMMAND SHOULD BE SET AS NC (ACTIVE OPEN). If set opposite of this, an
inadvertent start or failure to stop could occur should a discrete connection be lost or control wire come loose. IF THE
USER CHOOSES TO DISREGARD THIS SAFETY PRACTICE – THE RISK ASSUMED BY THE USER CAN BE
REDUCED BY ASSURING THAT OTHER SAFEGUARDS ARE USED TO INSURE PROPER START AND STOP
OPERATION. Depending on the application: This may include appropriate emergency stops, redundant wiring,
electronic guards and/or mechanical guards.
Failure to observe this precaution could result in severe bodily injury or loss of life.

frequency input

The preset frequencies may be programmed in two ways:
1. By programming desired preset frequency values via

PA21-

[Preset Frequency 1] through

PA35-[Preset Frequency 15].

2. By selecting the corresponding digital input setting and enter-

ing the desired frequency via

PF01-[Frequency Command].

Note: If any preset frequency input is active, all other frequency commands
will be ignored.

When this input is active, the 00{FW} or 01{RV} inputs will
respond to the frequency programmed via

PA38-[Jog Frequency].

The accel ramp is NOT active.
The stop command is determined by

PA39-[Jog Stop Mode].

Note: The Jog command will not work with 3-wire control.
