On the other hand the overload capability of the inverter is reduced with a higher carrier frequency. Both have to be considered when the setting is changed. Related Parameters Parameter No. C6-02 Name Factory Setting 3 Change during Operation No Control Methods V/f Q Open Closed Closed Loop Loop Loop Vector Vector Vector (PM) Q Q Q Carrier frequency selection Carrier Frequency Selection The factory setting is 8 kHz for units from 3. 7 to 22 kW and 5 kHz for units from 30 to 55 kW. However, if it necessary to change it, observe the following precautions: · If speed and torque oscillate at low speeds: Lower the carrier frequency. · If inverter noise affects peripheral devices: Lower the carrier frequency. · If leakage current from the Inverter too is large: Lower the carrier frequency. · If metallic noise from the motor is large: Increase the carrier frequency. 6 Carrier Frequency and Inverter Overload Capability If the carrier frequency is increased the rated current is decreased and vice versa (refer to page 9-6, Carrier Frequency Derating). The overload capability is always 150% of the derated inverter current for 30 sec. If this over load limit is exceeded the inverter trips with an inverter overload fault (OL2). Current limitation level at low speeds The Varispeed L7 limits the output current at low frequencies. This current limitation does not change with the carrier frequency selection. The current limitation in the low frequency range is as follows. 150% 140% 130% 120% 110% 200V Class 15kW 400V Class 30kW 200V Class 3. 7, 18, 30kW 400V Class 18, 22kW 200V Class 5. 5kW 400V Class 3. 7, 5. 5, 7. 5, 11, 55kW 200V Class11kW 200V Class 7. 5, 22 , 37, 45, 55kW 400V Class 4. 0, 15, 37, 45kW 0 1. 5Hz 3Hz 4. 5Hz 6Hz Output Frequency Fig 6. 1 Low frequency current limitation · If the torque at low frequencies is too low, check whether the current runs into the limitation explained ) and the V/f pattern (E1). If so, check the motor data settings (E2· If the current still runs into the limit it might be necessary to install a one size bigger inverter. · For selecting an inverter please consider the low frequency current limit as described above and select an inverter with an appropriate current margin. IMPORTANT 6-2 Control / Brake Sequence Up and Down Commands Travel start in Up or Down direction UP and Down commands are the travel direction information. To start in the elevator in Up or Down direction the following conditions have to be fulfilled: · At least one speed reference must be selected if digital inputs are used for speed reference selection. [. . . ] If the stall prevention functions are activated during acceleration or deceleration, it might be necessary to increase the acceleration or deceleration time. To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter. Handling Observe the following precautions during wiring or maintenance of an Inverter. Wiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W. Check all wiring and control sequences carefully. Magnetic Contactor Installation If a magnetic contactor is installed in the power supply line, do not exceed one start per hour. Switching more often can damage the inrush current prevention circuit. Maintenance and Inspections After turning OFF the main circuit power supply it can take several minutes before the DC bus is discharged completely. [. . . ]
