CSD Series Variable Frequency AC Drive
MOTORTRONICS
- 17 -
4.1.1 Terminals 1 & 2
Function: Fault/Trip Relay
Relay Contact to output alarm signal when protective circuit is activated.
Contact Rating: 250 VAC/1 Amp or 30 VDC/1 Amp
Refer to Fn 97 - Fn98 for programming the functionality of the fault
relay.
This allows remote indication of an drive trip condition and sends this
signal, depending on Fn98, to external logic. The keypad will flash a
fault code and the contact on TM2 - 1 & 2 (rated at 1 Amp, 250VAC or
30VDC) will change state when the drive indicates a fault signal such
as an over current (OC) or over voltage (OV).
4.1.2 Terminals 3 & 4
Function: (RUN/STOP, FWD/REV), (FWD/STOP, REV/STOP) or
Momentary START/STOP
(effective only in remote control Fn10=0001) as well as Reverse
lockout and Initial Frequency Operation .
The drive offers three methods of remote operation. This unique function
allows the use of either (run/stop, forward/reverse), (forward/stop,
reverse/stop) or momentary start/stop operation to meet different
application requirements. These three modes of operating are selected
via Fn03.
On/Off Control (only applicable when Fn10 = 0001): Depending on
the type of control, use one of the three following configurations for on/
off control. Note: The length of the wire connections between TM2
and the switches should be less than ten feet. Use dry contacts only
for connections. An optional 120 VAC interface card is available,
contact factory for more information.
4.1.2a Maintain FWD/STOP Switch and Maintain REV/Stop Switch
The diagrammed connections allow remote control to start/stop and
change motor rotation with Maintain Switches. One switch will function
as the forward run switch and the other will function as the reverse run
switch. Note: If reverse direction is not required, reverse switch is not
necessary.
4.1.2b Maintain ON/OFF Switch and Maintain FWD/REV Switch
The diagrammed connections allow remote control to start/stop and
change motor direction with Maintain Switches. One switch will
function as the on/off and the other switch will function as the forward/
reverse switch. Note: If reverse direction is not required, FWD/REV
switch is not necessary.
Normally Open = Program Fn98 to 0000
Normally Closed = Program Fn98 to 0100.
