Step 3. You may want to create a separate monitor screen for registers 206/1206
through 221/1221 and save it. This will allow you to recall the screen later,
without having to enter the entire list each time you need to monitor feedback
registers. (Note that registers 210/1210 and 212/1212 are not used.)
Step 4. Check the User Analog Input (register 214/1214) by applying an input signal
to the appropriate pins on the Resolver Feedback connector on the Resolver
and Drive I/O module and verifying that register 214/1214 displays an
appropriate value. Refer to instruction manual S-3018 for additional
information.
Step 5. Test the resolver. Be sure the resolver’s sine/cosine wires are connected per
the W/E diagrams. Monitor the value displayed in the Resolver Scan Position
register (215/1215). The value in this register can range from -32768 to
32767.
Rotate the resolver by hand (by turning the motor shaft if the resolver is
mounted/coupled), first in one direction, then in the other direction. The value
in the register should steadily increase in one direction and steadily decrease
in the other direction. If the value in the register does not change at all or if
the value does not increase/decrease smoothly, a problem may exist with the
resolver and/or its wiring.
Step 6. Test the external strobe, if used, as follows. Note that the resolver and
external strobe must be connected.
Force register 101, bit 8 (STR_ENA@, Enable External Strobe) on. Verify
that register 201/1201, bit 8 (STR_DET@, External Strobe Detected) is on.
Check the values displayed for registers 215/1215 (RES_SCN_POS%) and
216/1216 (RES_STR_POS%). The values displayed for these two registers
should be very close, if not identical, if the resolver has not turned. After you
have finished, unforce register 101, bit 8.
4.7.7.4 Testing the UDC Module Test Switch Register
This section describes how to test the UDC module test switch register. Use the
AutoMax Programming Executive software I/O Monitor function to display register
1000 in binary format.
Register 1000 reflects the status of the test switches and LED indicators on the UDC
module.
Step 1. Verify the function of the UDC push-button. When the push-button is
pressed, register 1000, bit 0 should be on. When the push-button is released,
this bit should be off.
Step 2. Verify the function of the UDC Test Switch. When the switch is in the
up-position, register 1000, bit 1 should be on. When the switch is in the
down-position, register 1000, bit 2 should be on. When the switch is in the
center position, both of these bits should be off.
