6-2 Starting Up Your System
If you are using an encoder attached to your L Option board, you
should also:
• Verify that the encoder feedback device is properly connected.
The encoder should be a quadrature device with a 12V input
power requirement and either 12V or 5V differential outputs.
Jumpers J1 and J2 on the L Option board must be set for the
desired output. The jumper settings for J1 and J2 must match.
• Verify that the L Option board, if present, is wired properly.
• Check the phasing of the encoder. A and A NOT as well as B and
B NOT must be properly terminated. This phasing is double
checked during the start up procedure.
Starting and Stopping the Motor
Repeated Application/Removal of Input Power
If your input voltage is:
Then jumper J8 (frames A1 – 14)/J4 (frames B – H)
should be across:
+5V DC Pins 1 and 2
+12V DC Pins 2 and 3

ATTENTION: The drive start/stop control circuitry
includes solid-state components. If hazards due to
accidental contact with moving machinery or
unintentional flow of liquid, gas, or solids exist, an
additional hardwired stop circuit is required to remove
AC line power to the drive. When AC power is removed,
there is a loss of inherent regenerative braking effect and
the motor coasts to a stop. An auxiliary braking method
may be required.
!
ATTENTION: The 1336 IMPACT drive is intended to
be controlled by control input signals that start and stop
the motor. A device that routinely disconnects and then
reapplies line power to the drive for the purpose of
starting and stopping the motor is not recommended. If
you use this type of circuit, a maximum of 3 stop/start
cycles in any 5 minute period (with a minimum 1 minute
rest between each cycle) is required. Ten minute rest
cycles must separate these 5 minute periods to let the
drive precharge resistors cool. Refer to codes and
standards applicable to your particular system for
specific requirements and additional information.
