Speed Command Selection And Hook-Up; Inhibiting The Control; Braking The Control; Current Limit / Fault Condition Latch - DART Controls 730 Control Series Instruction Manual

Inhibiting the Control

The 730 series control has a ¼" spade pin (P7) on the control that can be used to inhibit the control.
Tying this pin to the control common terminal (P1-6) will stop the control and override any other speed
command. Starting and stoping the control with the Inhibit input will not override Accel and Decel
settings on the 733 models.

Braking the Control

The 730B series control has a 1/8" spade pin (P10) on the control that can be used to brake the control.
Tying this pin to the control common terminal (P1-6) will quickly stop the control and override any other
speed command. Using brake to start and stop the control will override the Accel and Decel settings
of the 733BDC model. For a start and stop function with Accel and Decel, it is recommended to start
and stop the control via inhibit or disconnecting the pot wiper or signal wire, via a switch.

Current Limit / Fault Condition Latch

733BDC-CL Only
The 733BDC-CL has a 1/8" spade pin (P101) on the control's top board. If the motor is stalled for
any reason, this feature will not allow the motor to restart until the Current Limit Latch feature is reset.
Momentarily tying pin (P101) to the control common terminal (P1-6) will reset the Current Limit Latch
and override any other speed command. A Fault Condition Latch such as incorrect motor phase or
drive over-temperature will also activate this shutdown / latch feature and may be cleared the same
way (after fault condition is corrected).

Motor Direction Selection and Reversing

Terminal P1-8 on the 730 Series is the forward/reverse control. Allowing terminal P1-8 to remain
unconnected will let the motor turn in a particular direction. Connecting terminal P1-8 to P1-6 will
reverse the rotation direction. Either a jumper wire, switch, relay, or an open collector NPN transistor
can be used to make this connection. MAKE SURE WHEN THE MOTOR DIRECTION IS REVERSED
THAT THE MOTOR IS STOPPED. THE CONTROL ISN'T DESIGNED FOR PLUG REVERSING.
Sometimes it may be necessary to reverse the motor without using terminal P1-8. This is done by
stopping the motor and exchanging terminals P1-1 with P1-2 and terminals P1-10 with P1-11. This
will work with either a 60 or 120 degree motor.
If the motor draws an excessive amount of current in the reverse direction, this may be a motor designed
for only one direction. Consult with the motor manufacturer about this problem.
This completes a general hook-up for the 730 Series. The next task is to connect the motor to the control.

Power ON LED

The internal 12V supply has a green LED attached to it for an indication that the internal power supply
is operating and power is applied to the control.

Internal Fault LED

The internal fault LED (Red) indicates that there is a fault condition present with the control. One or
several of the following fault conditions can be present: invalid sensor input code, 60
jumper in wrong direction, over current condition (i.e. Current Limit set too low), undervoltage lockout
(i.e. +12V supply is less than 10.0V) or thermal shutdown (i.e. U2 is too hot). Typical fault conditions
are: invalid sensor attachment, 60
set too low.
