7.13 Relay Outputs Block
The Elite Pro has 3 customer configurable form C relay
outputs. Each relay can be configured to turn on (or energize)
at a programmable level and turn off (or de-energize) at a
different level. Thus the relay outputs have built in hysteresis
that can be completely controlled by the customer. Figure 25
shows the relay outputs in the off state.
Source (69-71, ICR)
The tag number of the parameter from which data is to
be taken.
Absolute Value (72-74)
When
Absolute Value
is True, the absolute value of
the source data is used to provide a positive only level.
This allows bipolar signals to operate the relays
properly regardless of the signal polarity.
On Value (75-77)*
The threshold level that the source signal must equal or
exceed in order for the relay to turn on (or energize).
Off Value (78-80) *
The threshold level that the source signal must equal or
fall below in order for the relay to turn off (or de-
energize).
Status (165-167, Read-Only)
The state of each relay can be viewed for diagnostic purposes. 0 indicates off, 1 indicates on.
Example - Relay Output
Setup Relay Output 2 to signal when the drive speed is above 50% with a hysteresis of 2%.
1. While the drive is stopped, go to Setup|Programming|Outputs|Relay|Relay Output 2 menu
section.
2. Set
Relay Output 2
Source to
Velocity Feedback
(193).
3. Set
Relay Output 2 Absolute Value
to True.
4. Set
Relay Output 2 On Value
to 50.00%.
* Note that the units and number of decimal places of this parameter will change to match that of the Source parameter.
