Motor Commutation Phasing (60° standard)
All standard (stock) brushless DC motors and gearmotors manufactured by
Bodine Electric Company are designed for 60° commutation. The factory
setting for our BLDC speed controls is also for 60° commutation. It is possible
to configure our BLDC stock controls to operate non-Bodine BLDC motors
and gearmotors with 120° commutation angle. To change the sensor phasing
output on our stock controls for 120° commutated gearmotors or motors, set
DIP switch number 6 to the “Off” position. Please note that further application
details must be considered to properly match a non-Bodine BLDC motor with
one of our stock BLDC controls. To avoid damage or system performance
issues, please consult our Technical Support staff at 773-478-3515 or via
E-mail: [email protected].
Line Fuse Installation
The control input is protected by factory-installed fuse (F1) shown in Figure 1.
It should always be replaced with a fuse of the same type and rating as
indicated in the chart in Figure 3.
Motor Fuse Installation
The control output contains a motor fuse (F2) shown in Figure 1. The rating of
F2 will vary with the size of the motor used. To determine the proper rating,
locate the first four digits of your motor’s type number on the motor nameplate.
Find the same four digits in the chart in Figure 3 and use only the fuse which is
recommended. The ABL-3912E and ABL 3913E are supplied with a motor fuse
kit containing all of the fuses listed in Figure 3.
Control Input Connections
The controls on the front panel of the ABL-3912E and ABL-3913E are used to
adjust motor speed, braking and direction of rotation. The controls are pre-
wired at the factory. Refer to the Operating Instructions for additional details.
AC Power Connections
AC power is supplied to the control through a pre-wired power cord. The
power cord should be the last connection made during installation and
always be disconnected first before servicing.
WARNING
The ABL-3912E and ABL-3913E must be plugged into a grounded AC outlet
using the power cord supplied. The outlet should be capable of providing
a continuous current of 12 amps. Do not defeat the safety feature of the
three-pronged plug. If your outlet is not a grounding-type AC outlet, have a
licensed electrician replace it with one that is.
