STOP!

Use only 10 V (peak to peak) or less resolvers. Use of higher voltage resolvers may result

in feedback failure and damage to the drive.

4.1.5 P5 - 24 VDC Back-up Power Input

P5 is a 2-pin quick-connect terminal block that can be used with an external 24 VDC (500mA) power supply

to provide “Keep Alive” capability: during a power loss, the logic and communications will remain active.

Applied voltage must be greater than 20VDC.

1 +24 VDC Positive 24 VDC Input

2 Return 24V power supply return

WARNING!

Hazard of unintended operation! When the enable input remains asserted, the “Keep Alive”

circuit 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.

4.1.6 P6 - Braking Resistor and DC Bus

P6 is a 5-pin quick-connect terminal block that can be used with an external braking resistor (the

PositionServo has the regen circuitry built-in). The Brake Resistor connects between the Positive DC Bus

(either P6.1 or 2) and P6.3.

DANGER!

Hazard of electrical shock! Voltage up to 480 VAC above earth ground is possible. Avoid direct contact

with live terminals and circuit elements. Disconnect incoming power and wait 60 seconds before

opening or servicing the drive. Capacitors retain charge after power is removed.
