Changing the DC Injection Brake Current Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function
Analog Input Terminal A3 Function Selection) to 6 (DC injection brake current), you can change the DC
injection brake current level using the analog input.
At 10 V input (voltage) or 20 mA input (current), 100% of the Inverter rated current will be applied.

Using an Emergency Stop
Set a multi-function input terminal (H1- ) to 15 or 17 (emergency stop) to decelerate to a stop at the decel-
eration time set in C1-09. If inputting the emergency stop with an NO contact, set the multi-function input ter-
minal (H1-
) to 15, and if inputting the emergency stop with an NC contact, set the multi-function input
terminal (H1- ) to 17.
After the emergency stop command has been input, operation cannot be restarted until the Inverter has
stopped. To cancel the emergency stop, turn OFF the run command and emergency stop command.

* The acceleration and deceleration settings range varies depending on the setting in C1-10. When C1-10 is set to 0, the acceleration/deceleration settings
range is 0.00 to 600.00 (seconds).
