In some instances it is desirable to delay the activation of a relay to assist with signal interlock for
example. This parameter sets the relay on delay for relay #2

G05 RLY CONFIGS
Several of the relay functions require parameters for their operation. Parameters include under and over
speed thresholds and calibration points for the percentage load warning output function.
G050 UNDER SPEED
G050 UNDER SPEED
20.0%
Range: 0.0...100.0 % of (C03 MAX Hz)
• Press to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press to accept the new value OR
• Press ESC to abandon the value change.
The G050 UNDER SPEED parameter is a motor frequency compare threshold. When the motor
frequency is below this value, the relay will energise. For example the > UNDER SPEED relay function
has been assigned to relay #2 (G040 RELAY #2 = UNDER SPEED) and G050 UNDER SPEED is set to
20%. When the output frequency goes below 20%, relay 2 will energise.
G051 OVER SPEED
G051 OVER SPEED
80.0%
Range: 0.0...100.0 % of (C03 MAX Hz)
• Press to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press to accept the new value OR
• Press ESC to abandon the value change.
