HP series

The HP series of DC motor controls provide accurate speed regulation, repeatable speed settings and large power capacity in a compact package. Designed for high stress industrial applications, the HP operates on three phase 230 or 460 VAC input. A full-wave, six SCR output power section delivers six pulses for every AC input cycle. This provides for smooth and cool motor operation, even in high torque, low speed applications.

The HP series is available in three basic types:

• BHP for forward operation without armature contactors
• FHP for forward operation with one armature contactor
• RHP for forward and reverse operation with two armature contactors and dynamic braking

FEATURES:

* Current sensing shunt provides a low-voltage signal proportional to the armature current for current monitoring circuits

* Power-on timer ensures power supply stability before startup by delaying startup by 200 milliseconds

* Optional automatic reversing remembers a reverse command and causes the motor to dynamically brake to zero speed, then reverse without an additional start command

* CMOS logic provides high noise immunity and low power consumption

* Built-in signal isolation permits connecting the speed pot control common to earth ground

* Digital ramp generator prevents phase mismatch between lines and eliminates ramp balance adjustments

* Line isolation provides impedance-isolated armature feedback and transformer-isolated shunt feedback signals

* Reed relays reduce electrical noise

* Latching network allows use of standard momentary contact push buttons for operator commands

* 50 or 60 Hz input selection

* Contactor timing and interlocks ensure zero current switching in models with contactors, extending contactor life

* LED indicators show phase loss protection, low line voltage protection, torque limit and forward or reverse operation

* Phase-insensitive AC input

* Control transformer (460 VAC models only)

* Independently adjustable acceleration and deceleration ramps

* Instantaneous overcurrent trip with LED fault indicator

* Anti-plug protection prevents start-up or reversal of the drive until the motor armature reaches zero speed

* Tachometer feedback input for 1750 or 2500 rpm motors with a 50 VDC/1000 rpm tach

* Remote/Local torque programming by jumper selection

* Speed command input of 4-20 milliamp or 0-6 VDC

* Standard options to meet most requirements
