5.6 ADDITIONAL FUNCTIONS
5.6.1 Configuration of the relay output function
To configure the function of the relay output with changeover contact (terminals NO-COM-NC) is necessary to set the parameter P420.01.
5.6.2 Configuration of the DO1 digital output function
To configure the function of the digital output (terminals DO1-GND) is necessary to set the parameter P420.02.
Here below are listed the most common functions.
Parameter Function Setting Description
P420.01 Relay output function 50 Function “running”: the relay switches when the output frequency of the VLB3 is
greater than 0.2Hz.
56 Function “error active”: the relay switches in case of active error.
70 Function “frequency threshold exceeded”: the relay switches when the output
frequency of the VLB3 is greater than the threshold set in P412.00.
78 Function “current limit reached”: the relay switches when the motor current is
greater or equal to the maximum threshold set in P324.00 (calculated as % of the
motor rated current P323.00).
Here below are listed the most common functions.
Parameter Function Setting Description
P420.02 DO1 digital output function 50 Function “running”: the DO1 output is activated when the output frequency of the
VLB3 is greater than 0.2Hz.
56 Function “error active”: the DO1 output is activated in case of active error.
70 Function “frequency threshold exceeded”: the DO1 output is activated when the
output frequency of the VLB3 is greater than the threshold set in P412.00.
78 Function “current limit reached”: the DO1 output is activated when the motor
current is greater or equal to the maximum threshold set in P324.00 (calculated
as % of the motor rated current P323.00).
