WARNING!
The connectors to terminal blocks A, B and C must be isolated signal voltages. Never
perform high voltage resistance or dielectric strength tests without first completely
disconnecting the drive from the circuit being tested.
Enable
Terminal C5 (ENABLE) is connected to terminal C9 (+24V) internally through a normally-opened auxiliary
contact on the DRV main contactor. The drive remains disabled until the main contactor poles are closed.
WARNING!
The drive must be disabled and power should be removed before servicing the
equipment. First stop the drive and make sure the main contactor has deenergized, then
remove power.
Thermistor
Terminals A1 and C1 are zero volt signal connections common to the return of the drive's +24 VDC
internally regulated supply. If the motor is fitted with overtemperature sensing devices such as thermistors
or thermostats, connect the devices in series between terminals C1 (0V) and C2 (THERMISTOR). If the
motor has an external blower motor, wire an auxiliary contact from the blower starter's overload trip
circuitry in series with the motor's over temperature device and terminals C2 and C1.
Program And Coast Stop
For a regenerative emergency stop (regen units only), connect terminal B8 (PROGRAM STOP) to
terminal C9 (+24 VDC) through a normally-opened contact of an emergency stop relay. Also connect
terminal B9 (COAST STOP) to terminal C9 through a time-delayed off, normally-opened contact on
the same emergency stop relay. Activating the E-Stop circuit r24 VDC from B8 and regener-
ates the motor power back into the main supply. The delayed-off contact on B9 (COAST STOP) acts
as a fail safe, allowing the drive to coast to a stop after the time delay.
For non-regenerative drives or for coast stopping with regenerative models, permanently jumper
terminal B8 to B9 and connect terminal B9 to +24 VDC (terminal C9) through a non-delayed, normally-
opened contact of the emergency stop relay. Upon activating an emergency stop condition, the drive
will coast stop immediately.
WARNING!
The emergency stop relay should not be considered part of the normal sequencing of the
system and should be triggered only in circumstances involving equipment damage or safety.
Dynamic Braking
The drive will dynamic brake if wired for coast stopping and a properly sized resistor is connected as
shown in Figure 3.20. The contactor in all 590 DRV Digitial drives through 250 HP includes a
normally closed, dynamic braking DC contactor pole. It is rated to carry full load armature current
upon closing. The start-stop circuitry should be designed to prevent the motor from restarting and the
pole from opening until after the motor reaches zero speed.
NOTE. The dynamic brake contactor pole is rated to make, but not interrupt DC motor
current. To avoid damaging the contact, interlock the drive's

logic to prevent the drive from restarting until the motor has reached
standstill.
For regenerative or non-regenerative drives, dynamic braking may be used as an alternative, emer-
gency stopping method. The wiring scheme is shown at the lower left in Figure 3.20.
