THERMAL
STD:
CONNECT FROM
TB2-8
TO
TB2-6**
Normally closed bi-metallic thermal switch in the motor. THE
MOTOR THERMAL SWICH MUST BE USED TO PROPERLY
PROTECT THE MOTOR! When the motor thermal switch opens,
the drive must be shut off to prevent damage to the motor
from overheating.
EMERGENCY
STOP
+24VDC
ON
TB2-7
STD: N/C PB
FROM
TB2-7
TO
TB2-6**
Voltage must be present to RUN or JOG. When removed,
ENABLE REQUEST is blocked immediately (see page 31) and
all control functions are disabled. Do not connect voltage to
terminal with permanent jumper. In RAMP STOP mode, this is
the only way to stop the drive.

Voltage must be present to maintain RUN mode after a
momentary START is removed. When voltage is removed, the
drive decelerates to zero speed at the DECEL rate and shuts
off if RAMP STOP jumper JP2 is installed. Otherwise drive
shuts off immediately and the motor coasts to a stop.
START /
RUN
+24VDC

TB2-4
STD: N/O PB
FROM
TB2-5
TO TB
2-4
Voltage must be applied to initiate RUN mode. When it is
removed, drive shuts off unless +24VDC is present at TB2-5.
RUN LED turns on when +24VDC is applied to TB2-4. RUN
LED turns off and RUN relay drops out when voltage is
removed from both TB2-4 and TB2-5.
RUN
CONTACT
TB2-1
AND
TB2-2
Normally open dry contact which closes when START is
energized and opens when RUN relay drops out (see above).
The RUN contact does not open on a FAULT unless the fault
removes the voltages from TB2-4 and TB2-5. The RUN contact
does not close on JOG and opens in RAMP STOP mode.
ZERO
SPEED
OUTPUT
: TB2-16
COMMON
: TB2-12
Open collector transistor output referenced to TB2-12. Rated
at 50 mADC @ 50 VDC max. This output operates only in RUN,
JOG, or RAMP STOP modes. The ZERO SPEED output turns
on at about 10 RPM and off at about 5 RPM. The ZERO
SPEED output shuts off if ENABLE LED shuts off.
JOG

C ON
TB2-13
STD: N/O PB FROM
TB2-5

TB2-13
Voltage must be applied to initiate JOG mode. JOG mode will
be maintained only as long as the voltage is present. When
the voltage is removed, the drive will go to RAMP STOP mode
if COAST TO STOP jumper JP2 is installed. Otherwise the
drive shuts off and the motor coasts to a stop.

Voltage must be applied to make motor go in reverse direction
(forward direction is defined as clockwise rotation of shaft
looking at output shaft end). In analog mode, applying or
removing voltage causes drive to decelerate to zero speed
and accelerate to set speed in opposite direction. In digital
mode, input frequency must be reduced to zero until motor
stops, then re-applied to go in opposite direction.

Optically coupled transistor output (isolated). Rated at 50

level. Output is off when any trip occurs.

COMMON
Apply voltage to switch to DIGITAL mode. TB1-10 and TB1-9
are electrically isolated from the board power supplies. The
negative side of the +24VDC used for the input must be
connected to TB1-9. External frequency must be applied to
terminal 11. Terminal 9 is also common for this frequency.
** NOTE:
TB2-6 is a dead terminal. It is used as a tie point.
