Initial Operation and User Interface
44/121
Operating Manual dryve D1, ST-, DC-, EC/BLDC-Motor Control System - V2.4
5.4.8.3 Braking Voltage Setting
The Braking Voltage sets the threshold to activate the Brake Resistor and dissipate the excessive energy.
To ensure a safe operation the Braking Voltage is equipped with a ON/OFF hysteresis of 1 V. To dissipate energy the counter-
voltage must rise above the set threshold plus 1 V. Tom stop the dissipation the voltage must sink below 50 V.
1.
Deactivate the dryve D1 via disabling the Digital Input 7 “Enable” (external signal or use of the switch on
“Inputs/Outputs” page)
12. Enter the desired Braking Voltage
13. Activate the dr
yve D1 via enabling the Digital Input 7 “Enable” (external signal or use of the switch on “Inputs/Outputs”
page)
NOTE
Setting the Braking Voltage to high might cause dissipating too less energy resulting in the error
GEFAHR!
-
Fire Hazard!
Incorrect Braking Voltage settings can cause a fire hazard!
If the Braking Voltage is set below the applied Load Voltage at X1.1, the Braking Resistors power rating is too low and the
power supply is not adequately dimensioned
an „Overload protection shut off“ after 1 second is not available
