If this is your first encounter with a Unidrive VTC
you may wish to try it out before installing it. From
this you can learn how to set up and control it. Ir
this case, refer to Safety Information in the installation

The Drive is supplied in either of two default
configurations to suit the continent in which it is
sold. The configurations are distinguished as
follows
EUR> European voltage, 50Hz AC Supply
The motor can be started and stopped, the
USA> USA Voltage, 60HZ AC supply

PID control
The drive can be configured by the use of macro 5
to operate with a frequency reference and an analog
feedback device for dynamically controlling the
speed under PId control (Terminal mode).
The Drive can be configured and fully controlled
from a system controller or PLc operating on a
RS232 or a 4-wire rS485 serial communications link
a Basic serial communications large option module or
an appropriate Second processor large option module
must be fitted in the drive. more information can
be obtained from a drive centre or distributor
listed at the end of this user guide
Serial communications can be used in conjunction
with Terminal mode or Keypad mode
The Unidrive vtc can be configured and controlled
from a Pc by use of the VtcSoft program which is
supplied on diskette and operat es under Microsoft
Windows M(version 3. 1 and later
A Basic serial communications large option module or
an appropriate Second processor large option module
must be fitted in the drive, a serial
