1.3 Function
Figure 1-3 shows the most important function
blocks of the unit:
•
From the mains voltage of 230 V AC or 115 V
AC the
intermediate circuit voltage of 70 V DC is
generated in the power unit.
•
The
chopper-type power supply unit provides
the supply voltages for the internal modules.
•
The
parameter switches are used to make the
basic settings for phase current, current reduc-
tion, current zero- setting, boost, direction rota-
tion and step angle (see section 2.5).
•
The "control electronics - power stage - current
controller" closed-loop circuit converts the
PULSE and DIRECTION input signals into the
output signals for driving the stepping motor.
The
control electronics block contains the ring
counter logic which defines the current pattern.
The current controller keeps the phase current
constant at the preset value.
•
The status of the equipment is recorded in the
Monitoring and Protection block. Any possible
errors are signalled externally via the fault indica-
tor and via the READY signal output (see sec-
tions 3.1.2 and 4.1).
For more details about the meaning and function of
the various control signals, see section 3.1
