Wiring requirements
●
Connect to signal source or control signal with multi-core shielded cable or stranded shielded wire.
●
The near-end of shielding layer of the case (end near the driver) shall be connected to the connector housing.
●
During wiring, the control cables shall be arranged more than 30cm away from the main circuit and strong power line (including
power line, motor line, relay, contactor connecting cable), and avoid parallel layout. Vertical wiring is recommended to prevent
malfunction of the driver due to interference.
●
Filter magnetic ring provided by the manufacturer shall be used for long distance wiring. It shall be installed at the side near the
driver.
FV terminal wiring example
CNC system uses bipolar (-10V ~ +10 V) analog output. The speed is determined by the value of the analog, the direction of
rotation is determined by polarity of the analog as shown in Figure 2-16.

Wiring of analog input signal
GH AC servo driver selects two analog input interfaces of FI and FV, as well as a group of power interface FS and FC for analog
input. Please see Table 2-13 for signal function description.
