WS5-5.281-00 - Power Drive - BERGER LAHR

The power drive WS5-5 has the following components :

• Current selection switch for selecting the motor phasecurrent;
• Parameter switch for selecting the functions: cur- rent zero-setting, boosting, current reduction, ro- tation direction, step angle;
• Voltage switch between 115 V AC and 230 V AC;
• LED display for signalling of faults
• Signal connection for driving of the power unit
via signal interfaces 1 and 2;
• Motor connection for a 5-phase stepping motor;
• Mains connection for the power supply
(115 / 230 V AC);
• Fasteners at the back of the equipment for fixing to mounting rails.

The power drive WS5-5 has been designed to be fixed to a mounting rail, i.e.:
• the equipment can be fixed to a mounting rail (TS 35 x 15) by means of the fasteners.
• all the operating controls, indicators and connec- tions are located on the front panel of the equipment.

Other characteristics include:
• Operation with mains power supply;
• Short-circuit protection of the power stage when
there is shorting between motor phases;
• Drive via signal interface 1 (with RS 422 signal
levels) and/or signal via interface 2 (with PLC
levels)
• Undervoltage, Excessive temperature and
phase monitoring of the power stage.

The purpose of the WS5-5 drive is to drive a 5- phase stepping motor up to a current of 2.8 A
(70 V DC). It is the link between a positioning con- troller (e.g. WP-311) or an SPC unit with indexer (e.g. IP 247, IP 267) and the stepping motor.
Up to 10 WS5-5 units can be operated in parallel via the high- impedance inputs of signal interface 1. The selection as to which WS5-5 is in operation (gate function) is made by signal interface 2.

The power drives of the WS5 series are designed for 5-phase stepping motors up to a maximum rated current of 2.8 A per winding.
