3.2 Wiring for the controller and the encoder
1. Each pin of CN1 and CN2 must be soldered and checked carefully for correct pin number
Check the adjacent pins after soldering to avoid being incidentally shorted circuit by the
solder or unused leads.
2. Wrap the soldered leads with shrinkable tubes to keep from being touched by each other.
3. If the leads from CN2 must be extended, care must be taken in the connection section and
proper shielding measures must be adopted to suppress EMI noise.
4. Do not stretch tight the leads of CN2 to avoid wiring faults of the encoder.
5. Power cables and signal lines should not be arranged in close parallel, and the leads for
control signals should be twisted and shielded.
Note: Be cautious of the length of the wiring and the measures for noise shielding if Mokon series is used
in position control mode. If not using the line driver type, the PULSE GND must be connected to
DGND, or the lost pulse fault may occur.

1. Do not bundle power and signal lines together in the same duct. Leave at least 30cm (11.81 in.)
between power and signal lines.
2. Use twisted-pair wires or multi-core shielded-pair wires for signal and encoder (PG) feedback
lines.
3. The maximum length for signal input lines is 3m (118.11 in.) and for PG feedback lines is 20m
(787.40 in.).
4. Do not touch the power terminals for 5 minutes after turning power off because high voltage may
still remain in the servo drive.
5. Make sure the Charge Indicator is out before starting an inspection.
6. Avoid frequently turning power on and off. Do not turn power on or off more than once per
minute.
7. Since the servo drive has capacitors in the power supply, a high charging current flows for 0.2
seconds when power is turned on. Frequently turning power on and off will cause main power
devices like capacitors and fuses to deteriorate, resulting in unexpected problems.
