| GENERAL FEATURES |
High reliability even at the maximum declared operating values. Galvanic separation between power and control circuits.
Control card one type only (interchangeable) for all model of the same series.
Protections against overvoltages, spikes, overloads and tacho failure.
Supply: line nominal voltage ± 10%, frequency 50/60 Hz ± 4%.
Feedback: selectable from tachogenerators or from motor armature.Speed control: double current-speed feedback loopRatio: 1 ÷ 100 typical with tacho - 1 ÷ 30 typical with armature feedback and Rxl compensation.
Stability (with tacho feedback): up to <0.1% of max speed at the following conditions: 0 to 100%, load ± 10%, line voltage ± 4%, line frequency ± 10°C ambient temperature. Analog inputs 10V, 1mA max; Digital input n.c. for control safety disable. Analog output 10V, 10mA max: for cascade operation. |

Adjustment of (by means of trimmers)
- Torque (0 - 100%)
- Max speed
- Acceleration ramp up and down
- Dynamic gain
Max operating temperature: 0 ÷ 55°C (models without fan) with 1.25% derating per °C above 35°C.
Air humidity: 90% max without condensation. |
