Par. J: Function for terminal 9 DC-STOP-input or NPN output
0-99 Same function as Par. H Relay function
101 DC-STOP-input (DC brake)
Par. L: Motor revolutions pr min at 50 Hz
PARAMETER L Set up the motors normal rotation pr min at 50 Hz. This is usually seen at the metal
plate on the side of the motor.
Note: This setting is not necessary if used as an ordinary frequency inverter (Par. P also)
Par. P: Encoder pulses pr. rotation
Set up the encoders pulse no pr rotation.
e.g. if a MIG encoders MIG105-14-50 is used (50 pulses pr rotation) Set the value to 50,00.
Par. 0*: Reference signal (program 0)
01 : 0-10volt (terminal 2 and 4) or
10KΩ potentiometer (terminal 1 – 2 – 4).
02 : Current input, 0-20mA (terminal 3 and 4)
03 : Current input, 4-20mA (terminal 3 and 4)
04 : (No function - reserved)
05* : 0-20mA / 0-10VDC 0-10V has priority over 0 – 20mA
06* : 4-20mA / 0-10VDC 0-10V has priority over 4 – 20mA
07 : Ramp generator (motor potentiometer) at terminals:
terminal 11: Increase of set point (Motor speed)
terminal 12: Decrease of set point (Motor speed)
Forward, Reverse, Stop and brake is still possible.
The setup speed is remembered until power off.
Up / Down ramping is done with the speed of parameter 3+4
08 : 0-10volt (terminal 2 and 4 ) controls the frequency.
0-10volt (terminal 3 and 4) controls the voltage / torque between 0 and 100% of normal
torque at the actual frequency.
* At 05 and 06 has 0-10V (potentiometer) the first priority. This function can used as automatic mode at
current signal and manual mode with 0-10V (potentiometer).
Manual regulation of the frequency in relationship to the reference signal
Press the UP or DOWN button and the green display will show └┘ for frequency above set point and ┌┐
for below set point. Note : This function is only available in program no 0 – Standard Frequency inverter
function.

NPN output.
Parameters to set: 7 / 8 / A
Note: When used as a NPN output do NOT
connect to +10V this will damage the inverter.
Data for NPN transistor: max. 36 VDC / 0,2A
