S200 Position Node Installation Guide
The above diagrams are applicable to systems implementing a solid-state load or relay
connected to an S200 Position Node output. Load LED and resistor or relay coil (reverse
diode) can be in ether leg of the power circuit.

The S200 Position Node has two analog outputs for use by the customer at J4. Each has a list of possible
assignments and a default value as listed in the S200 Position Node User’s Guide. The DAC (Digital to Analog
Converters) are OPAMP (Operational Amplifier) outputs and care should be taken to assure noise-free signal
reception. The range of each monitor is 0.5Vdc to 4.5Vdc and has an internal source impedance of 2k ohms. This
internal impedance limits to short circuit current to 2mA and can be a source of signal attenuation if too much load
is drawn from these outputs. These outputs are intended to feed instrumentation such as an Analog input to a
host or an oscilloscope for function monitoring. Each DAC Monitor output supplies a single-ended output voltage
referenced to the I/O RTN pin. The use of shielded, twisted pair wire is recommended if these circuits are to be
wired to another device. The shield should be tied to the frame of J4 at the drive and the frame of the receiving
equipment.

Available at J4 for the customer’s use are encoder equivalent output signals. These signals provide incremental
encoder performance for the motor driven by the S200 Position Node and can be used by a host controller or
monitor. The signals are differential driven and are RS-485 / RS 422 compliant. The use of terminating resistors at
the receiving end (120 ohm) is recommended. The output drivers are short-circuit protected. The encoder
resolution can be adjusted by switch S1 at the top of the drive or by the S200 OC Tools software. Refer to the
S200 User’s Guide for setup information on the resolution of the output.
Wiring for these signals should be done with individually twisted/shielded pairs. Shields should be tied at the
frame of J4 at the S200 Position Node and at the frame of the receiving equipment. An additional wire to tie the
two system’s DC common together is highly recommended to prevent damage from ground-shift spikes. Tie the
connection to any I/O RTN pin on J4 at the S200 PN.

Good motor wiring practice is a must when applying any PWM controlled servo motor drive to the motor. The
S200 PN uses PWM voltage control to the motor. The frequency of the PWM may vary according to the model
number. PWM systems switch high voltage at very fast rates. This voltage switching creates fast edged on the
voltage signals traveling down the motor cable to the servomotor. This switching voltage can couple capacitively
in both the cable and the motor creating high frequency current flows that must be controlled. Kollmorgen offers
highly engineered cables to provide the best control of these signals.
Should the user decide to wire the motor there are a few important recommendations that should be followed:
