Braking operation selection at the time of Real sensorless vector control
(Pr.850 = "0, 1")
• The braking operation at the time of the Real sensorless vector control can be selected between the DC injection brake
(initial value) or the Zero speed control.
By setting Pr.850 Brake operation selection = "1", zero speed control will be performed under the frequency set in Pr.10
DC injection brake operation frequency
NOTE
• Under Real sensorless vector control, when the X13 signal turns ON while Pr.11 = "8888", the zero speed control is activated
regardless of the Pr.850 setting.
• When restarting from brake operation at the time of Real sensorless vector control, set Pr.850 = "1" (zero speed control). In
case of setting value "0" (DC injection brake), it may take approximately 2 s from the time the start up command is input until
it actually is output.
