Chapter Six: Start up and Calibration
6.1 Introduction:
This chapter contains the procedure required for initial start up and amplifier calibration.
Both trapezoidal and sine/resolver modes can be configured to run in velocity mode and
current mode operations.
Required Equipment: Oscilloscope, voltmeter & battery box. The battery box serves as a
step input voltage command, applying and removing a flashlight battery can also be used for
this function. Glentek sells a battery box BB-700 which is ideal for this function.
6.2 Initial Start Up:
When applying power to start up your amplifier system for the first time, we recommend
you follow this procedure. If you have already gone through this procedure you can skip to the
appropriate calibration procedure.
1. Check for any loose or damaged components.
2. Check that all connections are tight.
3. Be sure that the motor mechanism is clear of obstructions. If the mechanism has limited
motion, e.g: a lead-screw, set the mechanism to mid-position.
4. Disconnect the signal and auxiliary inputs.
5. Be sure the Loop-Gain pot(s) are fully CCW.
6. Remove input fuses on the baseplate and apply main power. Check for the correct AC
voltage at fuse block. The DC Bus (amplifier supply-voltage) will be 1.4 times this value. If
voltage is correct, remove power and reinstall fuses.
7. Work on only one amplifier at a time.
6.3 Trapezoidal Mode Amplifier Calibration:
The following pots will be set during calibration:
Note: RV1-RV6 are 12-turn pots and RV7 is a single turn pot.
Pots Name of Port Note
RV1 SIG 1
(Differential Input
Signal Gain)
Sets the input voltage to RPM ratio, e.g. 10V=2000RPM (velocity
mode) or input voltage to torque ratio, e.g. 10V=10A (current
mode) required by your system for the differential signal input.
RV2 SIG 2
(Single-ended
Input Signal Gain)
Same as Signal 1 input, except it is for the single-ended signal
input.
RV3 TACH
(Tach Gain)
Used in conjunction with the compensation pot to set the system
bandwidth. Not used in current mode. Shipped set at 75%.
RV4 BAL (Balance) Used to null any offsets in system.
RV5 COMP
(Compensation)
Used in conjunction with the TACH pot to set the system
bandwidth. Not used in current mode. Shipped set at full CW
(minimum bandwidth).
RV6 I LIMIT
(Current Limit)
Sets the maximum motor current. Shipped set at full CW
(maximum current limit).
RV7 LOOP
(Loop Gain)
Used to shut off uncalibrated amplifiers. When the loop gain is
CCW, no current is delivered to the motor. Shipped set at full
CCW.
