This feature allows the user to switch resolutions at any time without having to keep track of sine/cosine location. Because of this, the On-Full-Step output of the IM805 can easily be used to monitor position. Configuration settings for the Microstep Resolution are located in Section 7 of this document, Interfacing and Controlling the IM805.
In the second part of the cycle the PWM reverts back DRIVE CURRENT to recirculating mode to increase RECIRCULATION efficiency and reduce current Figure 4.3: Non-Recirculating PWM ripple. IM805 Operating Instructions Revision R032306...
IM805 will execute the change before taking the next step. Only AFTER the change has been executed will the step be taken. If no change has occurred, the IM805 will simply take the next step. This feature works as an automatic debounce for the direction and microstep resolution select inputs.

Power supply cables must not run parallel to logic level wiring as noise will be coupled onto the logic signals from the power supply cables. If more than one driver is to be connected to the same power supply, run 22 IM805 Operating Instructions Revision R032306...
Since the output voltage of an unregulated power supply will vary with the AC input applied, it is recommended that an AC line filter be used to prevent damage to the IM805 due to a lightning strike or power surge. WARNING! Verify that the power supply wiring is correct prior to power application.
This means it has multiple phases wound in the stator and the rotor is dragged along in synchronism with the rotating magnetic field. The IM805 is designed to work with the following types of stepping motors:...

I M 8 0 5 S e c t i o n O v e r v i e w This section covers the interface connections, configuration and control signals of the IM805. Covered are: Layout and Interface Guidelines. Motor Power Connection (+V).
M o t o r P o w e r C o n n e c t i o n ( + V ) Figure 7.1 illustrates the motor power (+V) connection to two IM805 drives using a recommended IMS ISP200-7 unregulated switching power supply.
For any given motor, the output current used for microstepping is deter- mined differently from that of a half/full step driver. In the IM805, a sine/cosine output function is used in rotating the motor. Therefore, when microstepping, the specified phase current of the motor is considered an RMS value.

S e t t i n g t h e O u t p u t C u r r e n t The IM805 uses an internal 1 milliamp current source to establish the reference voltage needed to control the output current. This voltage is programmed by means of an external 1/8 watt or higher, 1 percent resis- tor connected between P2:2 (Current Adjust) and P2:3 (Power Ground).
WARNING! A current adjustment resistor is always necessary to keep the Driver and/or Motor in a safe operating range. DO NOT operate the IM805 Driver without a current adjustment resistor in place. Figure 7.2 illustrates the connection of this resistor. Table 7.1 lists the resistor values for the driver output current in 200 milliamp increments.
R e d u c i n g / D i s a b l i n g t h e O u t p u t C u r r e n t The IM805 has the capability of automatically reducing the current in the motor windings following a move.
If remote control of the output resolution is required, these signals are brought out on connector P1 on the IM805-34P1. This option is discussed in detail in Appendix A: Standard Connector Options. SW-1 Figure 7.4: MSEL Switch Showing 50 Microsteps/Step Selected...
I n t e r f a c i n g a n d U s i n g t h e I s o l a t e d L o g i c I n p u t s The IM805 has 4 optically isolated logic inputs which are located on connector P1. These inputs are isolated to minimize or eliminate electri- cal noise coupled onto the drive control signals.
���� Table 7.3: Recommended Input Current Limiting Resistor Values WARNING! The isolated logic inputs on the IM805 are internally limited to allow for an optocoupler supply voltage of +5 VDC. If using a higher voltage supply, a current limiting resistor must be placed in series with the input or damage will occur to the IM805’s input circuitry, rendering the drive inoperable.
Please note that the internal sine/cosine position generator will continue to increment or decrement as long as step clock pulses are being received by the IM805. This input is asynchronous to any other input and may be changed at any time.
Open Collector Interface. TTL Interface. We will also show IM805 inputs connected to the IMS LYNX modular mo- tion controller, which is a powerful machine control soulution. S w i t c h I n t e r f a c e A switch connected between the input and the opto supply ground will sink the input.
Figure 7.8 shows a TTL device connected to the enable input. This inter- face method may be used with any of the logic inputs. +5 VDC CONTROLLER Opto Supply P1:4 OUTPUT Enable P1:5 Figure 7.8: TTL Interface 46 IM805 Operating Instructions Revision R032306...
Figure 7.9 shows a LYNX Control Module and Differential I/O Module providing step clock, direction and optocoupler supply voltage to two IM805 drivers. The LYNX isolated I/O may also be used to control the enable and reset inputs, the MSEL inputs (IM805-34P1) and receive feed- back from the fault and fullstep outputs.
C o n n e c t i n g a n d U s i n g t h e F a u l t O u t p u t The IM805 has an open collector fault output located on P1:7. This output is non-isolated and has the ability of sustaining maximum driver voltage.
As noted in the drawing, this is only a representation of a possible application of the full step output. Additional interface circuitry may be required between the IM805 and the counter. Check the documentation provided by the manu- facturer of your counter for interface requirements.
B a s i c T r o u b l e s h o o t i n g In the event that your IM805 doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the prob- lem.

C o n t a c t i n g Te c h n i c a l S u p p o r t In the event that you are unable to isolate the problem with your IM805, the first action you should take is to contact the distributor from whom you originally purchased your product or IMS Technical Support at 860- 295-6102 or by fax at 860-295-6107.
This connector style would be advantageous in a scenario where the user desiresto plug the IM805 directly into a system PCB. NOTE: When mounting the IM805 directly to a PCB by wire wrap or receptacles, the Heat Sink temperature must still be kept at or below +70°...
I M 8 0 5 - 3 4 P 1 The IM805-34P1 connector configuration replaces the 8 position screw terminal at connector location P1 with a 34 pin header. Connector P2 is still an 8 position screw terminal. There are 2 key features that are added with this connector option: Microstep resolution select inputs (MSEL) on P1 allow for remote control of the output resolution.
Page 60
The microstep resolution is synchronized with the step clock input. If the resolution change does not fall on a full step, the IM805 will readjust itself at the next pulse that would overshoot the fullstep position. This feature allows the IM805 to readjust the motor position regardless of the output resolution selected during a resolution change.
S t e p C l o c k a n d D i r e c t i o n O u t p u t s Another key feature offered by the IM805-34P1 is the non-isolated step clock and direction outputs. These outputs will follow the step and direction inputs.
The P1 connector location uses 8 -0.025 square pins. This connector style is advantageous in a scenario where the user desires to wire wrap the IM805 directly into a system interface or use a receptacle to make the connections. Figures A.5 and A.6 show the pin dimensions.
I M 8 0 5 - 3 4 P 1 - 8 P 2 This option combines the features and potential uses of the IM805-34P1 and the IM805-8P2. The connector pins used for connector P2 are identical to those used on the IM805-8P2.
I n t e r f a c i n g t h e A d d i t i o n a l I / O o n C o n n e c t o r P 1 The MSEL inputs and Step/Direction outputs on the IM805-34P1-8P2 are interfaced in the same way as those on the IM805-34P1. See the part of this appendix pertaining to that model of the IM805 for interface and connec- tion details.
0.65 W/m-K and a maximum temperature rating of 180°C. One side of the TN-48 pad is adhesive and may be applied directly to the IM805 driver. The TN-48 pad eliminates the problems associated with using thermal grease. This pad are also included in the heat sink kit.
