Table 1: Control connections for the Models 2000C and 3000C.
Must be closed to RUN. Enables RUN circuits on
closing. On opening, disables all control functions
immediately. DO NOT JUMPER THESE TERMINALS,
especially if the RAMP STOP jumper is installed!
Normally closed thermal switch in the motor. Acts like
EStop on opening if the control circuits are wired in the
standard configuration shown in Figure 14. THE MOTOR
THERMAL SWITCH MUST BE CONNECTED IN
ORDER TO PROTECT THE MOTOR PROPERLY!
Must be closed to run. On opening, drive will ramp to
zero speed if RAMP STOP jumper is installed and control
is in analog mode. Otherwise, motor will coast to a stop.
In digital mode frequency input must be reduced to zero.
Momentary close to run. Must be open if momentary
STOP is used to terminal 5. RUN relay CR latches
between the terminals if terminal 5 is energized. Must be
held closed if two-wire connection is used (4 and 7).
Closes when terminal 4 is energized. Stays closed as long
as relay CR is maintained by RAMP STOP button on
terminal 5, or two-wire connection maintains connection
on terminal 4. DOES NOT OPEN ON FAULT!
Open collector transistor, C on 16, E on 12. Rated at 50
mA @ 50VDC. Turns on above 10 RPM and off below
10 RPM. May chatter at very low speeds.
Starts control in JOG mode (no latching). The control
operates while JOG circuit is closed. Speed set by pot on
board if in analog mode, otherwise frequency must be
supplied. JOG OVERRIDES RUN!
Close in analog mode to cause motor to go to zero speed
and return to set speed in the opposite direction. Open to
do same thing in opposite direction. May be applied at
any speed. Does not work in digital mode unless input
frequency is reduced to zero.
Isolated opticoupler transistor, C on 12, E on 13. Rated
at 50mA @ 80VDC. Turns on when bus is at proper
level. Turns off on trip condition.
Apply +24VDC at terminal 10 with respect to terminal 9
to change from analog to digital mode. Frequency must
be applied at terminal 11 with respect to terminal 9.
