Specific technical data of the DF51-322
The table below contains the specific technical specifications of
the single- and three-phase 230 V series, such as current, voltage,
and torque values.
Frequency and current monitoring • Connection of an analog display device: 0 to 10 VH, up to 1 mA for frequency or current
• Connection of a digital frequency meter
Signalling relay Relay contacts as two-way switch
Further features (not a complete listing) • Automatic voltage regulation
• Unattended start protection
• Variable amplification and output voltage reduction
•Frequency jumps
• Minimum/maximum frequency limitation
• Output frequency display
• Fault register available
• Freely selectable pulse frequency: 2 to 14 kHz
• PID control
• Automatic torque boost
• Second parameter set selectable
Safety features
• Overcurrent
• Overvoltage
• Undervoltage
• Overtemperature
• Earth fault (on Power On)
• Overload
• Electronic motor protection
• Current transformer fault
Ambient conditions
Ambient temperature –10 to +50 °C
From about +40 to +50 °C, the pulse frequency should be reduced to 2 kHz. The output
current should be less than 80 % of the rated current in this case.
Temperature/humidity during storage
–25 to 70 °C (for short periods only, for example during transport)
20 to 90 % relative humidity (non condensing)
Permissible vibration
Maximum 5.9 m/s
2
(= 0.6 g) at 10 to 55 Hz
Installation height and location
Maximum 1000 m above sea level in a housing or control panel (IP 54 or similar)
Optional accessories
• Remote operating units DEX-KEY-10, DEX-KEY-6, DEX-KEY-61
• Line reactor to improve the power factor
• RFI filter
• Motor reactor
• Sine-wave filter
• Field bus interface module CANopen (DE51-NET-CAN)

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.
