Safety Information
DANGER!
Hazard of electrical shock! Circuit potentials are up to 480 VAC above earth ground. Avoid direct contact with the printed
circuit board or with circuit elements to prevent the risk of serious injury or fatality. Disconnect incoming power and wait 60
seconds before servicing drive. Capacitors retain charge after power is removed.
STOP!
DO NOT connect incoming power to the output motor terminals (U, V, W)! Severe damage to the PositionServo will result.
Check phase wiring (U, V, W) and thermal input (T1, T2) before powering up drive. If miswired, severe damage to the
PositionServo will result.
STOP!
Use only 10 V (peak to peak) or less resolvers (P4). Use of higher voltage resolvers may result in feedback failure and
damage to the drive.
WARNING!
Hazard of unintended operation! When the enable input remains asserted, the “Keep Alive” circuit (P5) will restart the
motor upon restoration of mains power. If this action is not desired, then remove the enable input prior to re-application
of input power.
