Step 1: Connect speed potentiometer and Enable switch along with optional electro-mechanical
Brake, Stop, and Direction switches as shown in above diagram.
Step 2: Connect motor armature across A1 and A2.
CAUTION: Do not exceed 30 in-lbs. tightening torque on terminals
Step 3: Connect battery to (BAT+) and (BAT-), taking note the polarity.
Note: Upon initial battery terminal connection some sparking may occur. To eliminate this
sparking, temporarily place a resistor (typically 1kW) between BAT+ and its corresponding
wire to allow the drive to charge slowly.
CAUTION: Do not exceed 30 in-lbs. tightening torque on terminals
WARNING: Reverse polarity battery supply connection can cause permanent damage to the drive.
CALIBRATION
Trim Potentiometer Description and Adjustment
ACC (Acceleration): The Acceleration trim potentiometer adjusts the rate at which the
motor will accelerate. Turning the potentiometer clockwise decreases the rate at which
the motor will accelerate (i.e. the motor will accelerate slower as the trim potentiometer
is turned clockwise). This potentiometer has a range of 0 to 30 seconds.
DEC (Deceleration): The Deceleration trim potentiometer adjusts the rate at which the
motor will decelerate. Turning the potentiometer clockwise decreases the rate at which
the motor will decelerate (i.e. the motor will decelerate slower as the trim potentiometer
is turned clockwise). This potentiometer has a range of 0 to 30 seconds.
MIN SPD (Minimum Speed): The Minimum Speed trim potentiometer adjusts the
minimum speed the motor is allowed to operate at. Turning the potentiometer clockwise
will increase the minimum speed that is allowed with the Speed Potentiometer. This
potentiometer has a range of 0V to 8V for a 12V system and 0V to 14V for a 24V
system.
MAX SPD (Maximum Speed): The Maximum Speed trim potentiometer adjusts the
maximum speed the motor is allowed to operate at. Turning the trim potentiometer
clockwise will increase the maximum speed that is allowed with the Speed potentiometer. This potentiometer has a range of 8V to 12V for a 12V system and 14V to 24V for
a 24V system.
*Note: The output voltage of the drive will be no greater that the battery system
voltage.
REV MAX SPD (Reverse Maximum Speed): The Reverse Maximum Speed trim
potentiometer has the same function and ranges as the Maximum Speed trim potentiometer with the exception that it only adjusts the maximum speed in the reverse
direction and is independent of the forward maximum speed. This potentiometer has a
range of 8V to 12V for a 12V system and 14V to 24V for a 24V system.
*Note: The output voltage of the drive will be no greater that the battery system
voltage.
TQ LIM (Torque Limit): The Torque Limit trim potentiometer adjusts the amount of
current the drive will support. Turning the potentiometer clockwise will increase the
amount of current that can be supplied with a maximum of 60A (full clockwise) and
minimum of 2A (full counter-clockwise).
REG TQ LIM (Regenerative Torque Limit): The Regenerative Torque Limit trim
potentiometer, being that this drive is a regenerative type, adjusts the amount of current
that will be sourced back to the supply under deceleration or braking.
IR COMP (IR Compensation): IR Compensation is a feature of this drive that will
attempt to maintain the speed of the motor as the motor load increases. Turning the IR
COMP trim potentiometer clockwise increases the amount of IR Compensation that is
added.
OPERATION OVERVIEW
Enable (EN): By connecting the Enable pin to Common, the drive is permitted to
operate. If the enable pin is opened, or disconnected from common, the drive will
coast to a stop.
Stop (STP): When the Stop terminal is connected to Common, the drive will
regeneratively brake the motor to a stop, that is, the drive will convert the
mechanical energy of the motor into electrical energy, and use that electrical
energy to charge the battery. The deceleration trim pot (DEC) is bypassed with
this operation.
Direction (DIR): When the Direction pin is connected to Common the drive will
slow the motor to a stop and then reverse its direction according to the Acceleration (ACC) and Deceleration (DEC) trim potentiometers.
Brake (BRK): The Brake output is for use with an external electro-mechanical
brake. The drive only provides a ground for the brake; the positive voltage supply
for the mechanical brake must be sourced externally. The brake solenoid must be
connected as shown in the wiring diagram. The drive will only engage the brake
once the motor has slowed to a stop.
LED STATUS INDICATION
Green LED:
Unlit -- The drive does not have power or is asleep.
Blinking – The supply voltage is grater than 32V or less than 7V which is out of the
supply range.
Solid – The supply is within the range of the drive and is operating correctly.
Red LED:
Solid – The drive is in either Torque Limit or Regenerative Torque Limit.
Continuous Blinking – The drive is overheating. Provide more adequate ventilation
for the drive or decrease the load.
Two Blinks – The drive is approaching an under-voltage trip or has entered an
under-voltage trip.
Three Blinks - The drive has entered an Over-voltage trip.
Four Blinks – The drive has detected a short circuit on output.
To clear a Red LED fault, disconnect and then re-connect the Enable terminal
connection.
