6.6 Deceleration Trimpot (DECEL): The DECEL Trimpot controls the amount of ramp-down time when the
Main Speed Potentiometer is adjusted to a lower speed. The DECEL Trimpot is factory set to 2 seconds, which is
the amount of time it will take for the motor to decelerate from full speed to zero speed. To increase the
deceleration time, rotate the DECEL Trimpot clockwise. To decrease the acceleration time, rotate the DECEL
Trimpot counterclockwise. See Figure 15, on page 5.
Note: The deceleration time cannot be made less than the natural coast time of the motor and actual load.
7 OPERATION
WARNING! The Safety Warning, on page 1, must be read and understood before attempting to
operate this drive or severe injury or electrocution can result.
After the drive has been set up properly and wiring has been completed, the start-up procedure can begin. If the
AC power has been properly connected to the drive, the PWR LED should illuminate green. Before starting, be
sure that the Main speed Potentiometer is in the minimum position (fully counterclockwise). To start the drive,
rotate the potentiometer clockwise. The motor should begin to rotate.
Note: If the motor rotates in the incorrect direction, it will be necessary to disconnect the main AC power and
reverse the armature leads.
SAFETY WARNING! – PLEASE READ CAREFULLY!
This product must be installed and serviced by a qualified technician, electrician, or electrical maintenance
person familiar with its operation and the hazards involved. Proper installation, which includes electrical
connections, fusing or other current protection, and grounding, can reduce the chance of electrical shocks,
and/or fires, in this product or products used with this product, such as electric motors, switches, coils, solenoids,
and/or relays. Do not use this drive in an explosion-proof application. Eye protection must be worn and insulated
adjustment tools must be used when working with drive under power. This product is constructed of materials
(plastics, metals, carbon, silicon, etc.) which may be a potential hazard. Proper shielding, grounding, and filtering
of this product can reduce the emission of radio frequency interference (RFI) which may adversely affect
sensitive electronic equipment. It is the responsibility of the equipment manufacturer and individual installer to
supply this Safety Warning to the ultimate end user of this product. (SW 8/2012)
The drive contains electronic Start/Stop circuits, which can be used to start and stop the drive. However, these
circuits are never to be used as safety disconnects since they are not fail-safe. Use only the AC Line for this
purpose.
B e sure to read and follow all instructions carefully . Fire and/or electrocution can result due to improper use of this
product.
This product complies with all CE directives pertinent at the time of manufacture. Contact our Sales
Department for Declaration of Conformity. Installation of a CE approved RFI filter (KBRF-200A (Part No. 9945),
or equivalent) is required. Additional shielded motor cable and/or shielded AC Line cables may be required along
with a signal isolator (KBSI-240D (Part No. 9431) or equivalent).
