„ Changing the DC Injection Braking Current Using an Analog Input
If H3-09 (Terminal A2 Function Selection) or H3-05 (Terminal A3 Function Selection) is set to 6 (DC Injec-
tion Braking Current), the DC Injection Braking Current level can be changed using the analog input is
changed.
At 10 V input (voltage) or 20 mA input (current), 100% of the MxC rated current will be applied.

‹ Using an Emergency Stop (“Fast Stop”)
To have the MxC stop the machinery immediately as is done with an emergency stop, use the Fast Stop fea-
ture. Set a multi-function input terminal (H1-††) to 15 or 17 (Fast Stop) to decelerate to a stop at the deceler-
ation time set in C1-09. If inputting the emergency stop with an N.O. contact, set the multi-function input
terminal (H1-††) to 15, and if inputting the emergency stop with an N.C. contact, set the multi-function
input terminal (H1-††) to 17.
After the Fast Stop Command has been input, operation cannot be restarted until the MxC has stopped. To can-
cel the Fast Stop, turn off the Run Command and Emergency Stop Command.
„ Related Parameters
* The setting range for accel/decel times depends on the setting of C1-10 (Accel/Decel Time Setting Unit). If C1-10 is set to 0, the setting range is 0.00 to
600.00 (s).

Fast Stop Time Sets the time to decelerate from maximum
frequency to zero for the multi-function input
“Fast Stop” function.
Note: This parameter is also used by selecting
“Fast Stop” as a Stop Method when a
fault is detected.
