All data applies for a 4-pole threephaseasynchronous motor and the permissible ratings.hThe motor’s active power is the power available at thedrive shaft.DF51-322 device seriesDF51-322-… 025 037 055 075 1K1 1K5 2K2Assigned active power of motor in kW 0.25 0.37 0.55 0.75 1.1 1.5 2.2Apparent power of device in kVA at 230 V 0.5 1.0 1.1 1.5 1.9 2.8 3.9Primary side: Number of phasesPrimary side: Rated voltage240 V 0.5 1.0 1.2 1.6 2.0 2.9 4.1Single-phase/three-phase230 V ~ (180 V – 0 % to 264 V + 0 %), 47 to 63 HzSecondary side: Rated voltage Three-phase 200 to 240 V ~Corresponding to the primary side rated voltageIf the primary voltage drops, the secondary voltage also drops.Primary side: Rated current in A Single-phase 3.1 5.8 6.7 9.0 11.2 16.0 22.5Three-phase 1.8 3.4 3.9 5.2 6.5 9.3 13.0Secondary side: Rated current in A 1.4 2.6 3.0 4.0 5.0 7.1 10.0Efficiency (%) at 100 % secondary motor full load current 90.5 93.3 94.4 95.1 96.2 96.3 95.5Torque during startBraking torqueWith feedback to the capacitorsReduced braking torque at frequencies above 50 Hz 1)With DC brakingPower loss at rated operational current I ein W100 % from 6 Hz100 % at f F 50 Hz50 % at f F 60 Hz50 % at fF 60 HzBraking occurs at frequencies below the minimum frequency (minimum frequency,braking time and braking torque are user-definable).19 27 28 34 42 55 98Fan – – – – – j j20 % at fF 60 Hz1) If the regenerative braking torque is high, an external braking device with braking resistor must be used. Alternatively, you can use a DV51 withexternal braking resistor and – if required – optional keypad DEX-KEY-6… instead of the <strong>DF51.</strong> On the DV51 the braking device function is built in.193
