STARTUP AND CALIBRATION
This section contains the procedure required for initial start up and amplifier calibration. The
LCAM 5/15 series amplifier can be configured to run in velocity mode (x.x) and current mode
(y.y).
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.
Refer to the technical specifications page and the drawings in the appendix for the information
needed to supply the correct power and to wire the model you are starting up. An isolation trans-
former is needed for the multi-axis LCAM 5/15. An isolated power supply (unregulated is OK)
providing the necessary voltage is required for the LCAM 5/15 module. H2W can provide appro-
priate transformers and power supplies. Consult an H2W applications engineer or sales person
for assistance.
A. 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 (RV6 for LCAM 5/15). This will prevent the motor
from running away in velocity mode when power is applied.
6. Check for the correct AC voltage before connecting to LCAM 5/15 multi-axis amplifier. The
DC Bus (amplifier supply-voltage) will be 1.4 times greater than the AC value. If the voltage is
correct, remove power and connect AC source to amplifier inputs. For the LCAM 5/15 module
amplifier, check for the correct DC voltage before connecting to the amplifier power input.
7. Work on only one amplifier axis at a time for LCAM 5/15 multi-axis amplifiers.
