4 Parameter Settings and Functions
4.2.2 Position Reference

• When Vcc is +12 V: R1 = 1 k Ω
• When Vcc is +5 V: R1 = 180 Ω
Note: The following table shows the signal logic for an open-collector out-
put.
This circuit uses the 12-V power supply built into the SERVOPACK. Input is not insulated.
The noise margin of the input signal will decrease if the reference pulse is given using an open-collec-
tor output. Set parameter Pn200.3 to 1 if the position drifts due to noise.
„ Selecting a Reference Pulse Form
Use the following parameters to select the reference pulse form used.
The servomotor only rotates at an angle proportional to the input pulse.
When Tr1 is ON Equivalent to high-level input
When Tr1 is OFF Equivalent to low-level input
