5. Set
Relay Output 2 Off Value
to 48.00 %.
Relay Output 2 will energize when the drive speed equals or exceeds 50.00% and will de-
energize when the speed equals or falls below 48.00%. A hysteresis level was used to
prevent the relay from 'chattering' (continually energizing and de-energizing) when the
drive runs at 50.00% speed. Setting the Absolute Value parameter to True allows the
relay to work in the reverse direction as well.

7.14 Analog Outputs Block
The Elite Pro has 2 customer configurable analog voltage
outputs. Each output can supply up to 20 mA, and can
therefore be configured to serve as an open loop current
output if the load impedance is known.
Source (81, 82, ICR)
The tag number of the parameter from which data is
to be taken.
Gain (83, 84)
The analog output level is controlled by the Gain
setting. Nominally, a source value of 100% will produce 10V
output with the Gain set at 100%.

Bias (85, 86)
The Bias adjustment can be used to set a minimum output.
Absolute Value (87, 88)
If set to True, the output will be forced to a positive polarity regardless of the input signal
polarity.
Status (168, 169, Read-Only)
Each DAC output (12 bit + sign) can be viewed for diagnostic purposes. See below for
common readings.
