Specific technical data of the DF51-340
The table below contains the technical data specific to the three-
phase 400 V series (current, voltage, torque values, etc.)
With DC braking Braking occurs at frequencies below the minimum frequency
(minimum frequency, braking time and braking torque are user-
definable)
1) If the regenerative braking torque is high, an external braking device with braking resistor must be used.
Alternatively, you can use a DV51 with external braking resistor and – if required – optional keypad
DEX-KEY-6… instead of the DF51. On the DV51 the braking device function is built in.
