7.1.1: Auto Phase Warnings and Notes
Warnings
!
Motor Motion
Applying high voltage power to the amplifier before auto phasing may result in motor
motion. Be sure that motor motion will not cause injury.
Failure to heed this warning can result in equipment damage, injury, or death.
DANGER
!
High Voltage
Applying AC power to the STX amplifier applies high voltage to the amplifier-motor
connections and cabling. Protect personnel against electrical shock.
Failure to heed this warning can result in equipment damage, injury, or death.
Danger
Notes
• Do not connect a load to the motor before performing Auto Phase procedure.
• Always connect the motor using the same configuration.
• Wire properly and consistently.
• Connections are actually changed within the DSP, not at the motor terminals, and the results
are saved to flash memory. The actual wire configuration should NEVER change.
Phasing a stepper motor establishes positive direction for the motor and encoder.
