Electronic Drives
When used with electronic drives such as motor accelera-
tors, solid state starters, variable frequency drives, etc., an
isolating contactor must be installed between the motor
and the electronic drive device to protect the electronic
drive.
The coil of the contactor must be interlocked with Termi-
nals 3 and 4 of the SHORT-STOP; see Figs. 6.1 to 6.3.
Figure 6.4.4 With Electronic Drives
6.4.5
Single Phase
Refer to Fig. 6.4.1 (Single Direction, Single Speed.) Use
L1 & L2, rather than L1 & L3 for the power source.
Note that for a given voltage and horsepower rating, a
single-phase machine will draw greater current than the
three-phase equivalent. Be sure not to exceed either the
horsepower or current rating of the SHORT-STOP.

OPTIONS
7.1
Programmable Controller Mode
If your motor starter is controlled by a programmable
controller or other type of solid state switch, or if the
electronic brake does not activate after the motor has been
run, then:
a.
Connect Terminals S and W to a dry normally open
(N/O) auxiliary contact on all starter contactors.
b.
Set the "ILK SENSE" switch (located to the right of the
brake LED on the control board) to the OFF position.
7.2
Option L (45 sec. max. braking time.)
Maximum braking time is 45 seconds. No additional
wiring or controls involved. (Other braking times are also
available)
7.3
Option S (Higher Torque)
The maximum braking torque is higher than for standard
models. No additional wiring or controls are involved.
7.4
Option BD / Y (Brake Disable/Timeout)
Permits the brake to be disabled for certain purposes, such
as jogging or setup. To use this option, connect a DRY
contact or switch to Terminals B and Y. If the switch or
contact is closed during the run to brake transition, no
brake cycle will follow (motor coasts to a stop). If the
switch or contact is closed during a brake cycle, the brake
cycle will be terminated.
7.5
Option D (Dual-voltage operation)
On "dual-voltage" rated units, permits a single SHORT-
STOP to be used on either 230 OR 460 volts.
7.6
Option R (Braking using 3 motor windings)
May be used to excite all three windings. With this option,
the third motor lead is connected to Terminal 7. All other
connections are made as described for standard units.
