Introduction; Standard Features; Model Selection; Unpacking - DART Controls 730 Control Series Instruction Manual

Dart Controls 730 Series is a family of general purpose brushless motor controls. These controls
commutate power into standard 3 phase sensored brushless (BLDC) motors.
The 730 Series uses DC power sources of 11 to 15VDC or 18 to 54VDC, including batteries of 12,
24, 36, and 48 volts. The 730 Series will supply up to 7.5 amperes of continuous current to the motor
without an additional heat sink. With the -HS2 optional heat sink, the 730 series will supply up to 9
amperes of continuous current to the motor. It is available in either a basic open loop (730BDC), a
basic closed loop (731BDC), and a full featured closed loop (733BDC), and all can drive motors with
sensor spacings of 60 or 120 degrees.
A 14 position terminal strip connects the control to the DC power source, the motor, the speedpot, and
the forward/reverse control switch. A pluggable terminal strip (-P option) is also available. There is a
¼" spade pin that can be used for inhibiting the control. There is a 1/8" spade pin that can be used to
brake the control. The control's PC board carries the minimum speed, maximum speed and current
limit trimpots for the 730BDC, an additional gain trimpot for the 731BDC, as well as Accel and Decel
trimpots for the 733BDC.

Unpack the control and check for shipping damage. Locate the motor and its timing diagram. In addition,
the 5KΩ speedpot supplied with the chassis control, a DC power source, hook-up wires, and appropriate
tools for installation are needed. If the motor does not have a timing diagram, an ammeter of at least
a rating of 200% of the full load motor current and a small hand-held DC volt-ohmmeter are required.
