Product Parameters and Specifications
- Mains Connection:
- It supports permissible network configurations of TT and TN. The mains input voltage can be 3x 400 VAC to 480 VAC with a tolerance of ± 10%, or 3x 230 VAC ± 10%. The frequency range is 50 / 60 Hz ± 4%. The installed load has a maximum of 10 kVA, and the inrush current at 400 VAC is 7 A. The switch – on interval should be greater than 10 s. It also comes with an integrated line filter per EN 61800 – 3, category C3.
- DC Bus Connection:
- The DC bus capacitance is 470 µF.
- 24 VDC Power Supply:
- The input voltage is 24 VDC ± 25% with an input capacitance of 8200 µF. The current consumption has a maximum of 2.5 A plus the current for the motor holding brake.
- Motor Connection:
- The continuous current is 8.8 A eff. The continuous current may be reduced depending on the ambient temperature and installation elevation. For example, when the mains input voltage is 400 VAC, at a switching frequency of 5 kHz, there is no reduction; at 10 kHz, it reduces by 0.18 A eff per °C (starting at 54 °C); at 20 kHz, it reduces by 0.18 A eff per °C (starting at 30 °C). When the mains input voltage is 480 VAC, similar reduction rules apply but with different starting temperatures. Starting at 500 m above sea level, the continuous current reduces by 0.88 A eff per 1000 m. The peak current is 24 A eff, and the nominal switching frequency is 10 kHz, with possible switching frequencies of 5 / 10 / 20 kHz. The insulation stress of the connected motor per IEC TS 60034 – 25:2004 follows limit value curve A, and the max. motor line length is 25 m.
- Terminal Connection Cross Section:
- For flexible and fine – stranded wires with wire end sleeve, it supports a cross – section range of 0.25 to 4 mm². The approbation data includes UL / c – UL – US 30 to 10 awg and CSA 28 to 10 awg.
- Motor Holding Brake Connection:
- The response threshold for open – circuit monitoring is approximately 385 mA, with a max. output current of 1 A. The max. number of switching cycles is unlimited as it is implemented electronically.
- Braking Resistor:
- It has a peak power output of 7 kW and a continuous power of 200 W.
- Limit Switch and Reference Inputs:
- The circuit is of sink type with electrical isolation between input – acopos (yes) and input – input (no). The input voltage has a nominal value of 24 VDC and a maximum of 30 VDC. The switching threshold is low < 5 V and high > 15 V. The input current at nominal voltage is approximately 4 mA, and the switching delay is max. 2.0 ms. The modulation compared to ground potential is max. ± 38 V.
- Enable Inputs:
- The circuit is sink type with electrical isolation for input – acopos. The input voltage has a nominal value of 24 VDC and a maximum of 30 VDC. The input current at nominal voltage is approximately 30 mA. The switching threshold is low < 5 V and high > 15 V. The switching delay for enable 0 → 1 (ready for PWM) is max. 100 µs, and for enable 1 → 0 (PWM off) is max. 2.0 ms. The modulation compared to ground potential is max. ± 38 V.
