Safety stop function
 Hubs
Use hubs that meet the conditions listed below:
• Compliance with the IEEE802.3 (1000BASE-T)
• Support of the auto MDI/MDI-X function
• Support of the auto-negotiation function
• Switching hub (layer 2 switch)

A repeater hub is not available.
Operation is not guaranteed if the hubs do not meet these conditions.
Industrial switching hub
Type
NZ2EHG-T8
 Ethernet cable connection
• Connect or remove an Ethernet cable after switching the power of the inverter OFF.
• PORT1 and PORT2 do not need to be distinguished.
• When only one connector is used in star topology, either PORT1 or PORT2 is applicable.
• When using two connectors for line topology and ring topology, an Ethernet cable can be connected to the connectors in any combination. For example,
the cable can be connected between PORT1s or between PORT1 and PORT2.

Safety stop function
 Function description
The terminals related to the safety stop function are shown below.
Terminal
symbol
S1 For input of the safety stop channel 1.

S2 For input of the safety stop channel 2.

SIC Common terminal for terminals S1 and S2.

Outputs when an alarm or failure is detected.
So (SO) The signal is output when no internal safety circuit
failure exists.

SOC Terminal So (SO) ( open collector output ) common

In the initial status, terminals S1 and PC, S2 and PC, and SIC and SD are respectively shorted with shorting wires. To use the safety stop function, remove all the
shorting wires, and then connect to the safety relay module as shown in the following connection diagram.

At an internal safety circuit failure, the operation panel displays one of the faults shown on the next page.
NOTE
• Use terminal So (SO) to output a fault and to prevent restarting of the inverter. The signal cannot be used as safety stop input signal to other devices.
