Operation
To reverse motor direction:
To reverse the direction of motor shaft rotation while the
motor is running, set the DIRECTION switch to the opposite
position. If no DIRECTION switch is installed, open or short
the (D) and (E1) terminals on TB501, as required.
When a new direction is selected, there is no need to open
the enable input. The control will automatically decelerate
the motor to zero speed, reverse direction, and then
accelerate the motor back to the set speed. Acceleration
and deceleration rates are controlled by the ACCEL/DECEL
trimpot settings. If quicker reversing is needed refer to
applications notes section (page 51) for further detail.
* Do not set the torque limit setting above 150% of the motor’s
nameplate current rating.
7. If you attempt to startup and the yellow TQ LED comes
on, the control has entered torque limit mode. To avoid
this occurrence, you may:
a. increase the torque limit setting*, or
b. lengthen the acceleration time enough to
accomodate the needed starting torque by adjusting
the ACCEL trimpot.
