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.

1.2 Application/System

Integration

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
(Figure 1-2).

Motor types

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.

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.

NOTE

The 5-phase stepping motors are oper-
ated in pentagram connection (see
page 2-4).
