Digital Inputs

Digital inputs are connected at TB5.

Input Mode Select

A number of combinations are available by first programming
[Input Mode] to the desired control scheme (i.e. 2 wire, 3 wire or
Status). The remaining inputs can then be configured by
programming parameters 242-244 ([TB5 Term 22 Sel] - [TB5 Term
24 Sel]). Refer to the table on page 4–5 and the Digital I/O parameter
group in Chapter 7 for programming information.

If this mode is selected, the status of all inputs can be read at the [Input Status] parameter.

However, only “Stop/Fault Reset” will have control function.

These inputs must be present (reprogram if necessary) before drive will start.

Bit 0 of [Direction Mask] must = 1 to allow TB5 direction change/bipolar operation.

ATTENTION: A hazard of personal injury from
automatic restart exists with 2-wire control. 2-wire
control uses maintained Run contacts that act as both
Run (closed) and Stop (open) devices. Opening the Stop
contact (terminal 20) will stop the drive. If this contact
is reclosed, any fault will be reset. If a valid Start
command is still present, the drive will restart. Only use
2-wire control for applications outlined in NFPA79,
“Under Voltage Protection.”

If a 3-wire device (i.e. HIM) is also used, pressing the
HIM Stop key will also stop the drive. Releasing the
Stop key will clear any faults that are present, but the
drive will not restart without cycling the Start contact.
