2 DESCRIPTION
The CMI-01 is an interface unit for the CMS Control Motor System.
The unit is mounted into the card slots of the rack unit (CMR-01).
The CMI-01 Control Motor Interface is used in combination with the control motor driver, CMD-
RM1. Together they will form an interface to control 5-phase or 2-phase stepping motors.
Control Motor function:
The unit is controlled by activations of the control input modules of the Control Motor Rack, CMR-
01. The CMI-01 generates pulses in three different modes:
SINGLE STEP MODE: A single control input pulse, less than 500 ms, will generate a corresponding
number of pulses that will move the refiner disc 0.01 mm.
LOW-SPEED MODE: When the control input pulse is longer than 500 ms, it will generate a
frequency of pulses that will move the refiner disc with a speed of 0.05 mm/second.
HIGH-SPEED MODE: When the control input pulse is longer than 500 ms, and high speed input is
active, it will generate a frequency of pulses that will move the refiner disc with a speed of 0.25
mm/second.
Due to variation of the thread pitch on the control rod, 4 different sets of pre-adjusted frequencies can
be selected depending of the adjusting screw and type of refiner. (See settings in chapter 4, page 4).
Both the low-speed and the high-speed frequencies can also be adjusted by multi-turn potentiometers
in the front of the unit.
When zero torque input signal (DI+CMT) is active, the unit will generate an output signal to the
CMD-RM1 or CMD-RM2 unit, and that will enable the holding torque of the motor.

5. ADJUSTMENTS
5.1 HIGH SPEED
Connect a high impedance digital voltmeter to the connector "HIGHSPEED" (+)
and "COMMON" (-).
Read the voltmeter value and adjust the high-speed potentiometer.
Values can be adjusted between 0.5 and 1.5V. If 1.0V is chosen, the speed of the
axial movement will be 0.25 mm/s. If the stepping motor is working while
adjusting, the change will be affected first upon the next activation. 0.5 V on the
DVM corresponds to 0.125 mm/s, 1.0 V to 0.25 mm/s and 1.5 V to 0.375 mm/s.
5.2 LOW SPEED
Connect a high impedance digital voltmeter to the connector "LOWSPEED" (+)
and "COMMON" (-).
Read the voltmeter value and adjust the low-speed potentiometer.
Values can be adjusted between 50 and 150%. If 100% is chosen, the speed of
the axial movement will be 0.05 mm/s. If the stepping motor is working while
adjusting, the change will be affected first upon the next activation. 0.5 V on the
DVM corresponds to 0.025 mm/s, 1.0 V to 0.05 mm/s and 1.5 V to 0.075 mm/s.
