Cable Specification; Network Configuration - Toshiba TOSVERT VF-S15 Series Manual

3.6. Cable Specification

Recommended cable specification is below
Selected recommended cable is below.
Manufacture : JMACS Japan Co., Ltd.
Distributor
* Fix a cable so that a communication connector may be not taken the weight of wire.

3.7. Network configuration

Make up the network as follows.
- Transmission/reception signals (CAN_H, CAN_L)
Make up the communication path by connecting twisted cables with shield.
- Signal common (CAN_GND)
GND is the signal common.
- Grounding the shield of cable (CAN_SHLD)
Connect the all shield lines of network cable. The shield shall be grounded at one end only prevent currents
from being created.
- Termination resistor
A termination resistance of 120 ohms plus or minus 5% shall be connected at each of the two ends of the
segment medium.

N.B.: RJ45 connector shield case is connected to the drive frame grounded in the drive.
Keep the network cables 20cm or more separate from the power cables to prevent from malfunctioning
due to electromagnetic noise.
