Inspect the motor and rotate the shaft when the motor is not connected. If

you feel any rubbing or there are any dents on the motor, there is prob

ably an alignment problem and the motor may need to be replaced.

If the rotor was removed from the stator, it could have been demagne

tized. The motor would need to be replaced.
If you still cannot solve the problem, the size of your power supply (volt

age output) may need to be greater. When a step motor rotates, it acts

like a generator pumping voltage (back EMF) back into the drive. Back

EMF rises as motor speed and inductance increase and can cause a stall.

The solution is to either change from a series to a parallel connection

(series connections quadruple inductance) or use a power supply with a

higher output voltage.

Problem:

The motor doesn’t produce any holding torque.

Solution:

Make sure that line power is on, the drive is powered up, and

the motor phases are connected correctly to the drive.

Problem:

The motor (actuator) oscillates back and forth at low speeds.

Solution:

This is due to resonance, common between 1-4 rps. If this is

observed with no load, add a load to the motor (the load will dampen out

resonance). Changing from full-step to half-step or microstepping will also

solve resonance problems.

Step and Direction Drives

Note: Please read your manual first before and during your setup. Bimba

manuals, available at

www.bimba.com/OLE/manuals

, are short, to the

point, and comprehensive.

Problem:

The drive’s power LED does not illuminate when power is ap

plied.

Solution:

Check the fuse and replace if necessary with one of the extra

fuses included with your drive. If you have no fuses or continuously blow

fuses, call Bimba Technical Support. Check your power supply to be sure

it is not providing an excessively high voltage to the drive.

Problem:

The motor runs then suddenly dies. The connections are cor-

rect.

Solution:

Turn off power. Refer to your motor wiring diagram. Discon

nect the motor. Using an ohmmeter, measure the resistance between the

A+ and A- and B+ and B- terminals. The reading should be in the mega-

Ohms. If resistance is low, the H-bridge is damaged and the drive must

be returned on a RGA (Returned Good Authorization). If the resistance is

normal, inspect the board for any visible damage to the components and

check the motor for a short circuit in the windings.
