2.5.6.1 Logic Inputs
The logic input circuits can be powered either from the internal +24 volt DC power
supply or from an external +24 volt DC power source. The internal +24 volt DC power
supply is available at the Regulator board terminal strip (see figure 2.16). If an
external power source is used, only the common must be connected to 24 V
COM on the Regulator board (terminal 15).
2.5.6.2 Logic Outputs
The logic output circuits are normally-open (when de-energized) relay contacts. When
energized (contacts closed) the three circuits indicate the following drive conditions.
Terminals are on the Regulator board terminal strip.
• Running Terminals 27 and 28
• Alarm Terminals 29 and 30
• No Fault Terminals 31 and 32
2.5.6.3 Analog Inputs
The three customer analog inputs are Manual Mode Reference, Automatic Mode
Reference, and Analog Tachometer Feedback. At their full range, these inputs are
converted at 12 bits plus sign.
2.5.6.4 Analog Outputs
The two metering analog outputs are available at Regulator board terminals 24, 25,
and 26. Terminal 25 is the common connection for both output signals. The selected
signals for both meter outputs are averaged (filtered) over 100 msec to reduce meter
fluctuations.
Parameter METER OUT 1 SELECT corresponds to terminals 24 and 25. Parameter
METER OUT 2 SELECT corresponds to terminals 25 and 26. Refer to these parameters
in Appendix B for additional drive test points that ban be configured to source Meter
Outputs 1 and 2.
!
ATTENTION:Connecting an external power source to any of the +24
volt connections (terminals 1, 7, 11, and 14) on the Regulator board
terminal strip will damage the drive. DO NOT connect the external power
source on the +24 volt connections on the Regulator board terminal strip.
Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
