Note: 1. Pin numbers in parenthesis () indicate signal grounds.
2. The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) output signals can be
changed via parameters. /CLT, /VCT, /BK, /WARN, and /NEAR signals can also be
changed. Refer to 4.3.4 Output Circuit Signal Allocation.
2.4.4 Interface Circuits
This section shows examples of SERVOPACK I/O signal connection to the host controller.
„ Interface for Reference Input Circuits
Analog Input Circuit
Analog signals are either speed or torque reference signals at the impedance below.
• Reference speed input: About 14 k Ω
• Reference torque input: About 14 k Ω
The maximum allowable voltages for input signals is ±12 V.

26 Positioning completed (output in Position Control Mode): Turns ON when the number
of error pulses reaches the value set. The setting is the number of error pulses set in ref-
erence units (input pulse units defined by the electronic gear). 4.5.3
