WebPak 3000 DC Drive Application Workbook, Version 1.1
3.1 The Speed Loop Reference
Refer to figure A.4 in Appendix A of the software manual (D2-3444) as you set up the
speed loop reference.
The setup of the speed reference depends on the control source selected. The control
source selections are:
KEYPAD
- The drive uses the reference from the OIM.
Important:
If you select
KEYPAD
as the control source, the drive can be used to
regulate speed only.
TERMBLK
- The drive uses the reference from the Regulator board terminal strip.
SERIAL
- The drive uses the reference from a serial device (for example, a PC running
WebPakCS software).
NETWORK
- The drive uses the reference from the network.
þ
To select the control source:
▲
If you are using the WebPakCS software to program the drive, you configured
the control source during the initialization process by setting
CONTROL SOURCE
SELECT
(P.000).
▲
If you are using the OIM to program the drive, select the control source
using
If the
CONTROL SOURCE
(P.000) =

:
▲ Specify the line speed signal type in
LINE SPEED REF SELECT
(P.103). The
choices are:
ANALOG
FREQUENCY
IN
- The frequency input is typically used to daisy-chain
multiple drives.
If

terminals 19(+) and 20(-) on the Regulator board.
