FlexPak 3000 DC Drive Software Reference
4.1.1 Configuring the Keypad (OIM) Speed Reference
CONTROL SOURCE SELECT
must be set to
KEYPAD
to use the keypad reference. When
manual mode is selected, you enter the speed reference manually through the
OIM
.
See the
OIM
manual for information on setting the speed reference through the
OIM
.
The keypad reference cannot be configured to less than
MINIMUM SPEED
(P.003) or
greater than
MAXIMUM SPEED
(P.004). The default value of the keypad reference is
MINIMUM SPEED
(P.003).
4.1.2 Configuring the Analog Auto Reference
CONTROL SOURCE SELECT
must be set to
TERMBLK
,
SERIAL
, or
KEYPAD
to use the analog
auto input as a speed reference. When you use this speed reference, the signal is the
analog auto reference from terminals 19(+) and 20(–) of the Regulator board. Note
that this input can also be used as a current reference to the current minor loop.
You must specify the type of signal that is at terminals 19 and 20 by setting
ANLG AUTO
SIGNAL TYPE
(P.100) and jumpers J10 and J12 on the Regulator board. The settings of
ANLG AUTO SIGNAL TYPE
(P.100) and the jumpers must be the same. See the hardware
manual for information on setting the jumpers.
The drive used the
ANLG AUTO GAIN ADJ
(P.101),
ANLG AUTO SIGNAL TYPE
(P.100), and
ANLG AUTO ZERO ADJ
(P.102) to scale the analog auto reference signal from terminal 19
and 20 of the Regulator board to produce the
ANALOG AUTO REFERENCE
(P.188) signal.
!
ATTENTION:
When switching from auto to manual or from manual to
auto, the drive will ramp to the reference level provided by the new source
at the rate specified by
ACCELERATION TIME
(P.001) or
DECELERATION TIME
(P.002). Be aware that an abrupt speed change might occur, depending
on the new reference and the rate specified in these parameters. Failure
to observe this precaution could result in bodily injury.
ANALOG AUTO REFERENCE
(P.188)
The analog reference
value in auto mode.
This is the value
output by the drive
after all hardware and
software scaling.
