Description
Sets an offset, as a percentage of the full scale range of the input, which is applied to the
analog input signal
Value in percent of the full scale range of the input
Example: If the analog input signal format is 0-10V, offset = 20% .
An analog input signal level of 7 Volts gives the following result :-
Analog input level (%) = 7/10 = 70%
Result = 70-20 (%) = 50%
Scales the analog input by this factor, (as a percentage of the full scale range of this input).
Example: If parameter 1304 ANALOG INPUT 2 FORMAT is set for 0 – 10V, and the scaling
factor is set to 200.0%, a 5 volt input will result in the drive running at maximum speed as set
in parameter 2008 MAX SPEED LIMIT
Status information indicated through relay output and relay operating delays
Selects the function assigned to Relay Output 1. The relay has three output terminals, Logic 1
indicates the relay is active, and therefore terminals 14 and 15 will be linked together.
Note : When using settings 4 – 7, parameters 3203 USER RELAY 1 UPPER LIMIT and 3202
USER RELAY 1 LOWER LIMIT must be used together to control the behavior. The output will
switch to Logic 1 when the selected signal exceeds the value programmed in parameter 3203
USER RELAY 1 UPPER LIMIT, and return to Logic 0 when the signal falls below the value
programmed in parameter 3202 USER RELAY 1 LOWER LIMIT.
Logic 1 when the motor is enabled.
Logic 1 when power is applied to the drive and no fault exists.
Logic 1 when the output frequency matches the setpoint frequency.
Logic 1 when the drive output frequency to the motor is exceeds 0.0Hz.
Logic 1 when the motor speed exceeds the adjustable limit. (See note above)
Logic 1 when the motor current exceeds the adjustable limit. (See note above)
Logic 1 when the motor torque exceeds the adjustable limit. (See note above)
Logic 1 when the signal applied to the Analog Input 2 exceeds the adjustable limit. (See note
above)

Logic 1 when the drive has tripped and the display shows the fault code.
Logic 1 when both STO inputs are present and the drive is able to be operated.
Selects the function assigned to Relay Output 2. The relay has three output terminals, Logic 1
indicates the relay is active, and therefore terminals 17 and 18 will be linked together.
Note : When using settings 4 – 7, parameters 3206 USER RELAY 2 UPPER LIMIT and 3205
USER RELAY 2 LOWER LIMIT must be used together to control the behaviour. The output will
switch to Logic 1 when the selected signal exceeds the value programmed in parameter 3206
USER RELAY 2 UPPER LIMIT, and return to Logic 0 when the signal falls below the value
programmed in parameter 3205 USER RELAY 2 LOWER LIMIT.
Logic 1 when power is applied to the drive and no fault exists
Logic 1 when the output frequency matches the setpoint frequency
Logic 1 when the drive output frequency to the motor is exceeds 0.0Hz
Logic 1 when the motor speed exceeds the adjustable limit
Logic 1 when the motor current exceeds the adjustable limit
Logic 1 when the motor torque exceeds the adjustable limit
1 Logic when the signal applied to the Analog Input 2 exceeds the adjustable limit
