D u a l P W M C i r c u i t The IM2000 contains a unique dual PWM circuit that efficiently and accurately regulates the current in the windings of a two phase stepping motor. The internal PWM accomplishes this by using an alternating recirculating/non-recirculating mode to control the current. -

the non-recirculating pulse widths to compensate for changes in supply volt- age and accommodate a wide variety of motor inductances. This method also allows for the use of very low inductance motors with your IM483H/IM805H driver, while utilizing a 20kHz chopping rate which reduces motor heating but maintains high efficiency and low current ripple. -

Page 25: Table 5.1: Im483H/Im805H Motor Power Supply Specifications
Stepping motor drivers are designed with the intent that a user’s power supply output will ramp up to greater than or equal to the minimum operating voltage. The initial current surge is substantial and could damage the driver if the supply is undersized. -
Page 26: Recommended Ims Power Supplies
R e c o m m e n d e d I M S P o w e r S u p p l i e s IMS has designed a series of low cost miniature unregulated Switching and Linear Supplies that can handle extreme varying load conditions. This makes them ideal for stepper motor drives and DC servo motors. -

R e c o m m e n d e d I M S M o t o r s IMS stocks the following 1.8° hybrid stepping motors that are recommended for the IM483H/IM805H. All IMS motors are CE marked. For more detailed information on these motors, please see the IMS Full Line catalog or the IMS website at http://www.imshome.com. - Page 33 I M S I n s i d e O u t S t e p p e r M o t o r s The new inside out stepper (IOS) motor was designed by IMS to bring versatil- ity to stepper motors using a unique multi-functional, hollow core design. This versatile new motor can be converted to a ball screw linear actuator by mounting a miniature ball screw to the front shaft face.

Page 34: Motor Wiring
M o t o r W i r i n g As with the power supply wiring, motor wiring should be run separately from logic wiring to minimize noise coupled onto the logic signals. Motor cabling exceeding 1’ in length should be shielded twisted pairs to reduce the trans- mission of EMI (Electromagnetic Interference) which can lead to rough motor operation and poor system performance overall. -
Page 35: Lead Motors
8 L e a d M o t o r s 8 lead motors offer a high degree of flexibility to the system designer in that they may be connected in series or parallel, thus satisfying a wide range of applications. S e r i e s C o n n e c t i o n A series motor configuration would typically be used in applications where a higher torque at low speeds is needed. -
Page 36: Lead Motors
6 L e a d M o t o r s Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operation. The higher speed configuration, or half coil, is so described because it uses one half of the motor’s inductor wind- ings. -
Page 37: Lead Motors
4 L e a d M o t o r s 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance. In setting the driver output current, multiply the specified phase current by 1.4 to determine the peak output current. PHASE A PHASE A PHASE B... -

Page 39: Motor Power
M o t o r P o w e r Pins 5 (+V), and 2 & 8 (GND) on connector P2 are used to connect motor DC power to the IM483H/IM805H. Two local capacitors are needed. These must be located as close to the IM483H/IM805H’s motor power input pins as pos- sible to ensure stable operation. -

+ 5 V D C I n p u t The IM483H/IM805H requires an external regulated +5VDC, ±5% power sup- ply. The supply is connected between P2:6 (+5VDC Supply) and P2:4 (Power Ground). A 68 microfarad 10V tantalum capacitor must be placed as close to the IM483H/IM805H as possible between the +5VDC input pin (P2:6) and ground. - Page 41 ply the specified per phase (or unipolar) current rating by 1.4 to determine the peak output current. 2) When configuring the motor so the full coil is used (i.e. connected from end-to-end with the center tap floating (higher torque configuration)) use the per phase (or unipolar) current rating as the peak output current.
