Analog Outputs
The HPV 900 Series 2 has two programmable
differential analog output channels. The two
analog output channels were designed for
diagnostic help.
For more information on
programming the analog output channels, see
Analog Outputs C4 Submenu on page 106.
The analog output channels are bipolar and
have a voltage range of

10VDC.
Available with the analog channels is multiplier
gain parameters (ANA 1 OUT GAIN and ANA
2 OUT GAIN) and a bias or offset parameters
(ANA 1 OUT OFFSET and ANA 2 OUT
OFFSET). These parameters are used to scale
the user’s analog outputs to the proper range
for the drive software. The formula below
shows the scaling effects of these two
parameters.

Electrical Installation
Input Power Connections
Terminals: R, S, and T provide connections for
AC input power.
Motor Lead Connections
U, V, & W terminals provide connection points
for the motor leads.
DC Choke Connections
Ter1 and +2 provide connection points
for a user supplied DC choke. A two position
removable link is provided to the pair of
terminals. With this link, the drive can be
operated without the use of a DC choke. All
HPV 900 Series 2 drives contain internal DC
reactors.
Brake Resistor Connections
Terminals B1 and B2 provide connection
points for an external user supplied braking
resistor. Connect the external brake resistor
between terminals B1 and B2. Terminals: +
and - are the positive and negative rails of the
DC bus (see Figure 27, Figure 28, Figure 29,
and Figure 30).
Equipment Grounding
A terminal block is provided for the required
user supplied equipment grounding.
Control Circuit
Observe the following precautions:
Refer to Figure 8 on page 25 for completing
encoder connections; analog inputs; logic
inputs; and logic outputs at the HPV 900
Series 2’s Control Board.
IMPORTANT
Parameter adjustments will have to be made
for the specific analog input, logic inputs, and
logic outputs to be used for the installation.
