Using An Emergency Stop - Omron VARISPEED G7 Instruction Manual

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-
eration time set in C1-09. If inputting the emergency stop with an NO contact, set the multi-function input ter-

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.
