I.INTRODUCTION

The Baldor ID5601-WO Adjustable Speed Drive is a variable speed control in a NEMA-4X / IP- 65 washdown and watertight enclosure. It is designed to operate 208 - 230 Volt 3-phase AC induction motors through 3.6 Amps RMS. The sine wave coded Pulse Width Modulated (PWM) output, which operates at a frequency of 8 kHz, provides high motor torque, high efficiency and low noise. The control operates from 115 or 208/230 Volt 50/60 Hz single phase AC line input.

Due to its user friendly design, tailoring to specific applications is easily accomplished via selectable jumpers and trimpot adjustments. However, for most applications no adjustments are necessary.

Main features include adjustable RMS Current Limit and I2t Motor Overload Protection. In addition, Adjustable Slip Compensation provides excellent load regulation over a wide speed range. Electronic Inrush Current Limiting eliminates harmful AC line inrush current and Adjustable Linear Acceleration and Deceleration make the drive suitable for soft-start appli- cations. Additional features include holding torque at zero speed and ride-through which pro- vides a smooth recovery to the previous set speed during a momentary power loss.

Standard front panel features include diagnostic LEDs for power on and control status, a Start/Stop Switch, Power On/Off Switch and a Main Speed Potentiometer. Other features include a Barrier Terminal Block to facilitate wiring of the AC line and motor, adjustable trimpots (MAX, MIN, ACCEL, DECEL, COMP, CL, BOOST) and selectable jumpers (line voltage, motor horsepower, auto or manual reset modes, motor frequency, frequency multiplier, fixed or adjustable boost).

Optional accessories include a Forward-Stop-Reverse Switch, Signal Isolator, and Auto/Manual Switch. Quick-connect terminals are provided for easy installation of all accessories.

STANDARD FEATURES

Motor Overload Protection (I2t)* – Provides motor overload protection which prevents motor burnout and eliminates nuisance trips.

Electronic Inrush Current Limiting – Eliminates harmful inrush AC line current during startup.

Dual Voltage Input – The control operates from 115 or 208/230 Volt 50/60 Hz single phase AC line Input.

Horsepower Selection – The control contains a horsepower selection jumper which elimi- nates the need to recalibrate the CL trimpot for different motors.

Short Circuit Protection – Shuts down the control if a short circuit occurs at the motor (phase-to-phase).

Regeneration Protection – Eliminates tripping due to bus overvoltage caused by rapid deceleration of high inertial loads.

Slip Compensation with Boost – Provides excellent load regulation over a wide speed range.

Start/Stop Switch – Provides electronic start and stop.

Power On/Off Swiitch – Disconects the AC line.

Ride-Through – Provides smooth recovery to the previous set speed during a momentary power loss.

Diagnostic LEDs – Power on (POWER) and control status (STATUS).

Barrier Terminal Block – Facilitates wiring of motor and AC line.

Protection Features – Undervoltage and overvoltage protection. MOV input transient pro- tection. Microcontroller self-monitoring and auto reboot. Short circuit protected phase-to- phase at motor.

Industrial Duty Die-Cast Aluminum Case – Available in white FDA approved finish.

Holding Torque at Zero Speed – Resists motor shaft rotation when the control is in stop mode.

Note: * UL approved as an electronic overload protector for motors.
