DC Controls
Baldor's VersaFlex DC Drives combine digital motor control circuitry with reliable SCR power devices to provide advanced DC motor control and protection. Onboard operator control allows easy programming of control set-up and operating parameters. Optional feedback expansion boards enhance drive capabilities by allowing the control to continuously monitor a motor-mounted AC or DC tachometer or incremental encoder. Controls from 35 to 165A continuous include built-in line contactor, control logic supply, and fuses (line, armature, field supply, and control logic). Other options include internally mounted blower motor starter, and communications boards. VersaFlex DC and Regen DC controls can be configured using Workbench D.
Features:
VersaFlex DC control provides unidirectional (single quadrant) digital control
VersaFlex Regen DC provides bidirectional (4 quadrant) regenerative control
220 to 500V line input (±10%) and 50 or 60 Hz input for worldwide use
Operator keypad is remote mountable to 10 feet (3m)for optimum ergonomic placement
Expansion boards provide connection to RS-485,Modbus, Profibus DP,DeviceNet networks
One Way
One-way DC controls are designed to operate permanent magnet or wound field motors. Some controls offer optional switch for reversal. Stopping of a motor with a one-way control should be done by dynamic braking, some controls offer the Forward-Brake-Reverse switch for this purpose too.
