These terminals connect the 240/120 VAC power provided by the user to the drive’s power output stage bus to drive the motor. For single phase operation use any two of these terminals and leave the third terminal open.These terminals provide the connection points for an external resistor to absorb regenerated energy from the motor. An external regeneration resistor goes from + B to R. -Bus (-B) on TB1-9 is usually left open.
External Regen Resistor
The table below lists the recommended values for an external regen resistor. To order from Pacific Scientific use part number REG-833. Note: Regen Resistance MUST be in the range of 11.25 Ω to 13.75 Ω.For safety it is recommended that the resistor be mounted on a grounded panel or use a grounding wire connected to a mounting screw. The terminals of the resistor must not be grounded.Wait 10 minutes after Bus Power is removed for the bus cap voltage to decay to a safe level before touching regen resistor or wiring. The voltage on the bus caps can be monitored with a voltmeter from +BUS (TB1-7) to -BUS (TB1-9).
Motor Power
PE (TB1-10) Motor Case Ground This termination provides a convenient point for the motor ground connection and motor power wire shield. Local electrical code may require using the Earth Ground Chassis stud for this function. U, V, W (TB1-11, 12, 13) Motor Phase These three terminations provide the 3-phase power output to the brushless motor. Observe motor polarity on these connections. For example, connect U on the drive to U on the motor
