Functions
Inputting EMR to the digital input lets the motor go into "Emergency Shutoff" status (or free-run
status).
This status continues while EMR is turned on or until a reset signal is input.
To use the Inverter to control the mechanical brake (used for cranes, etc.), you need to connect the
safety output of the external safety relay to the brake control circuit in series.
Note 1: For the signal lines for the safety relay and emergency shutoff input, use shielded coaxial
cables with 2.8 mm or less in diameter and 2 m or less in length. The shield must be
grounded.
Note 2: All inductor parts such as the relay and contactor must have overvoltage protection circuits.
With DIP switch S8 turned on, multi-function input 3 is automatically allocated to the emergency
shutoff signal EMR input terminal, and 4 to the reset signal input terminal. In this case, EMR is
allocated to function code C003, and reset (RS) to C004 automatically, and you cannot change
these parameters manually. The following table shows the status of DIP switch S8 and the
allocation of the multi-function input.
In short, when DIP switch S8 is turned on, input terminal 5 automatically switches to "No function
allocated" status. To allocate a function to terminal 5 in this status, use the function mode.
If DIP switch S8 is turned off later, input terminal 3 switches to "No function allocated" status. To
allocate a function, again use the function mode.
You can reset Emergency Shutoff status only via the dedicated input terminal (terminal 4 in the
above table). The STOP/RESET button on the Digital Operator cannot be used for resetting
Emergency Shutoff status.
* When DIP switch S8 is ON, the EMR function is forcibly set to NC contact, and the RS function to
NO contact.(Parameters C013 and C014 are ignored)
