• Wires - 18 to 20 gage recommended • Wire cutter/stripper • An appropriate DC power supply. Warning: Do not apply power until all connections are made. The DRV-4 accepts power supply voltages from 24 to 48 VDC, while the DRV-8 accepts power supply voltages from 24 to 75 VDC. The current demand will never exceed double the motor current (see Table 3, Amps column). However, the DRV will convert a high voltage low current power supply into a lower voltage higher current power supply. A 24V 4A supply will perform similarly to a 48V 2A supply. Use Table 7 below as a guideline. Use unregulated power supplies without overvoltage protection to avoid problems with regeneration during rapid deceleration.

Page 8: Connect The Dc Power Supply To The Driver
Warnings: • Do not install where ambient air is more than 104° F. • Do not install where there is no air flow • Do not install where drive can get wet. • Do not install where electrically conductive material can fall on the driver. • Drives must be mounted at least one-half inch apart. b. Connect the DC power supply to the driver -- Do not apply power Warning: Observe proper polarity when connecting wires. I. Make sure the power supply is not on. Connect V+ and V- from the power supply to the V+ and V- terminals of your driver. II. Ensure a proper earth ground connection by using the screw on the left side of the chassis. If using an external fuse, we recommend the following in-line with the V+ connection: DRV-4: 3AG, 4 amp (Littlefuse 313004P) DRV-8: 3AG, 6.25 amp (Littlefuse 3136.25P) -

Page 14: Fault Output
j. FAULT output The DRV drives feature a digital FAULT output. This output closes to signal a fault condition. This output can be used to drive LEDs, relays and the inputs of other elec- tronic devices like PLCs. The “+” (collector) and “-” (emitter) terminals of the output transistor are available at the connector. This allows you to configure the output for current sourcing or sinking. Diagrams of each type of connec- tion follow. Do not connect the output to more than 30 VDC. The current through the output terminal must not exceed 80 mA. 5-24 VDC 5-24 VDC Power Supply Power Supply – –... -
Page 15: Set Step Pulse Type
k. Set step pulse type Most indexers and motion controllers provide motion commands in the “Step and Direction” format. The Step signal pulses once for each motor step and the direction signal commands direction. However, a few PLCs use a differ- ent type of command signal: one signal pulses once for each desired step in the clockwise direction (called STEP CW), while a second signal pulses for counterclockwise motion (STEP CCW). The drives can accept this type of signal if you remove the cover and move jumper S3 from the “1-2” position to the “1-3” position. Factory default is the 1-2 position. As you can see in the image, the jumper terminals (2, 1, 3) and S3 and S4 designators are printed in white on the circuit board. Jumper S4: noise filter Jumper S3: step pulse type Shown in 1-2 position Shown in 1-2 position l. Step pulse noise filter Electrical noise can cause the drive to think that one step pulse is two or more pulses, resulting in extra motion and inaccurate motor and load posi- tioning. To combat this problem, the drive includes a digital noise filter on the STEP and DIR inputs. The default factory setting of this filter is 150 kHz. -

Page 18: Troubleshooting Guide And Faq
If windings are shorted, the motor must be replaced. Problem: Actuator operation is stiff, seems to be binding. Solution: Check for dents on the body tube, motor end bell, and dam- age to the square rod. If there are signs of visible damage, the actuator or motor or both may need to be replaced. Dents on the motor shaft or endbells may cause the rotor to seize or rub, producing binding and stiff operation. While the nut of the OLE actuator is self-lubricating, rod lubri- cations is recommended at regular intervals. Use Bimba HT-99 grease. Problem: Can I use switches with my OLE for end of stroke sensing? Solution: All OLE actuators have magnetic pistons. OLE actuators can use the same switches as Original Line pneumatic cylinders. Refer to the Bimba catalog for switch recommendations. Problem: The motor gets hot. Solution: Step motors tend to run hot (the actual maximum case tem- perature is 80° C). However, the motor should not get too hot to touch. If it is overheating, the drive current may be set too high. All standard OLE step motors are 8-wire motors. Refer to Table 3 in this manual for... - Page 19 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.
- Page 20 Problem: The motor does not move when a step signal is sent to the drive. Solution: If the enable input is on (low with respect to a 5-24 volt signal), it will disable the motor. Do not connect anything to the enable input if there is no reason to disable the motor. Problem: The motor will not run slow enough with a potentiometer con- nected to my drive (it has an internal oscillator). Solution: Some drives’ internal potentiometers cannot be adjusted to zero speed. Check the specifications in the manual that came with the drive. Problem: At startup, the motor does not run although the wiring is cor- rect. Solution: Make sure that dip switches and jumpers are set properly. Read your driver manual carefully. Problem: System not working properly. Solution: Troubleshoot by replacing the drive and see if the problem persists. Please read your drive manual before and during your setup.
