CONTROL WIRING DIAGRAMS

The CVW300G2 has two sealed connectors, XC9 and XC10, which
are used to wire control signals from the drive.

BASIC CONNECTION FOR FIRST POWER-UP

WEG motors used with the CVW300G2 are supplied with a speed
sensor (encoder), and it must be connected to the CVW300G2 for
the reading of the signals according to
Table 7: Encoder wiring diagram

NOTE!
In order to connect the encoder to the CVW300G2,
you must additionally short XC10 pins 3, 5 and 7,
together with XC10 pin 8. The WEG´s encoder supply
is done by the +15 V aux power supply, in XC10
connector, pin 9.
When present, the HMI Interface must be connected to the
CVW300G2 by means of a shielded cable with a female DB9 terminal,
according to Table 8 on page 9.

In order to purchase a HMI accessory, refer to the user manual.
Most electric drive applications need an accelerator. It is
recommended to use electronic accelerators with potentiometer
with minimum impedance of 2 kΩ and with the wiring suggested in
Figure 6 on page 9.
