Rockwell Automation 1397 DC Drive Firmware 2.xx - Manual (Page 52)

2–34 Installation
Publication 1397-5.0 — June, 2001
TB–11 POWER – A 24VDC supply is available at this pin.
TB–12 MOTOR BRUSH WEAR – Level sensitive input that
causes a motor brush wear alarm (0 = ALARM). The
Drive can still operate under this condition. This input
CANNOT be masked.
TB–13 MOTOR THERMOSTAT – Level sensitive input that
causes a motor thermostat fault (0 = FAULT). The
Drive will be faulted while this input is true. This input
CANNOT be masked.
TB–14 POWER – A 24VDC supply is available at this pin.
TB–15 COMMON – A 24VDC common supply is available at
this pin.
TB–16,17,18 ANALOG REFERENCE 2 – Fixed
± 10VDC analog
reference.
TB–19,20 ANALOG REFERENCE 1 – Signal type selected by
Anlg In 1 Type (P.128) parameter (0–10 VDC,
±10
VDC, 4-20mA, 10–50mA) and hardware jumpers on
the regulator board (J10 and J12).
TB–21,22,23 ANALOG TACHOMETER IN – Use of #21 or #22 is
determined by J14 hardware jumper on the regulator.
ATTENTION: If motor rotation is changed by
reversing either the motor armature lead connections or
the field connections, the Pulse Encoder feedback
polarity on the B and NOT B leads must be reversed. If
a DC Tach is used, feedback polarity must also be
reversed. Failure to observe this precaution could result
in personal injury or damage to equipment.

1. Wiring the Coast Stop Circuit
The 1397 Drive has the capability to accept an input from either a
24VDC or 115VAC contact (If the 115 VAC Control Option Board is
installed). The contact must be normally closed and will typically be
a Stop pushbutton. Refer to the following paragraphs for connection
information. This input cannot be masked and is always active.
ATTENTION: The Run/Stop and customer interlock
circuitry in this Drive is composed of solid-state
components. A hardwired Coast to Stop circuit must be
used with this Drive. For 115VAC control, this
circuitry may be added on the optional 115VAC Control
Board.
