Displayed in Quick Programming Mode when motor 2 is set for a multi-function input. 6-38 Machine Protection Control Mode and Carrier Frequency Settings Carrier frequency settings are restricted as listed in the following table according to the control mode selection. Control Mode Carrier Frequency 1: 2. 0 kHz 2: 5. 0 kHz 3: 8. 0 kHz 4: 10. 0 kHz 5: 12. 5 kHz 6: 15. 0 kHz F: Any setting* Detailed settings are available in C6-03, C6-04, and C6-05. 1: 2. 0 kHz 2: 5. 0 kHz 3: 8. 0 kHz 4: 10. 0 kHz 5: 12. 5 kHz 6: 15. 0 kHz F: Any setting* The upper limit of the carrier frequency is determined by C6-03. 1: 2. 0 kHz 2: 4. 0 kHz 3: 6. 0 kHz 4: 8. 0 kHz V/f control with or without a PG Open-loop vector control 1 or Flux vector control Open-loop vector control 2 * The upper limit of the carrier frequency depends on the Inverter capacity. Carrier Frequency Setting Precautions When selecting the carrier frequency, observe the following precautions. · Adjust the carrier frequency according to the cases shown below. If the wiring distance between Inverter and motor is long: Set the carrier frequency low. (Use the following values as guidelines. ) Wiring Length C6-02 (carrier frequency selection) setting 50 m or less 1 to 6 (15 kHz) 100 m or less 1 to 4 (10 kHz) Over 100 m 1 to 2 (5 kHz) If speed and torque are inconsistent at low speeds: Set the carrier frequency low. If leakage current from the Inverter is large: Set the carrier frequency low. If metallic noise from the motor is large: Set the carrier frequency high. · When using V/f control or V/f control with PG, you can vary the carrier frequency according to the output frequency, as shown in the following diagram, by setting C6-03 (Carrier Frequency Upper Limit), C6-04 (Carrier Frequency Lower Limit), and C6-05 (Carrier Frequency Proportional Gain). 6-39 Carrier Frequency C6-03 C6-04 Output frequency × C6-05 × K* * K is the coefficient determined by the set value in C6-03. C6-03 10. 0 kHz: K=3 10. 0 kHz > C6-03 5. 0 kHz: K=2 5. 0 kHz > C6-03: K=1 Output frequency E1-04 Max. Output Frequency Fig 6. 32 · With vector control, the carrier frequency is fixed to the Carrier Frequency Upper Limit in C6-03 if user- set or by the carrier frequency set in C6-02. · To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0. · If the settings are as shown below, OPE11 (Constant setting error) will occur. If Carrier Frequency Proportional Gain (C6-05) > 6 and C6-03 < C6-04. · Depending on the carrier frequency setting, the Inverter's overload level may be reduced. Even when the overload current falls to below 150%, OL2 (Inverter overload) will be detected. The Inverter overload current reduction level is shown below.

In the open-loop vector control method, the user-set value is applied to the torque limit by calculating internally the torque output by the motor. Enable this function if you do not want a torque above a specified amount to be applied to the load, or if you do not want a regeneration value above a specified amount to occur.

This torque limit setting is enabled even when the analog input signal generates forward torque while the motor is operating (regeneration). Setting the Torque Limit in Constants Using L7-01 to L7-04, you can set individually four torque limits in the following directions: Forward drive, reverse drive, forward regeneration, and reverse regeneration. 6-41 Set the Torque Limit Value Using an Analog Input You can change the analog input level torque limit value by setting the torque limit in multi-function analog input terminals A2 and A3. The analog input terminal signal level is factory-set as follows: Multi-function analog input terminal A2: 4 to 20 mA Multi-function analog input terminal A3: 0 to 10 The following diagram shows the relationship between the torque limits. Output torque Positive Positive/negative torque limits Forward torque limit No. of motor rotations Forward operation Regenerative torque limit Negative torque limit Positive/negative torque limits Negative Regenerative torque limit Reverse operation Fig 6. 35 Torque Limit by Analog Input Setting Torque Limits Using Constants and an Analog Input The following block diagram shows the relationship between torque limit using constants and torque limit using an analog input.

To make the torque limit value during 10 V or 20 mA input 150% of the rated torque, set the input terminal gain to 150. 0 (%). Adjust the gain for multi-function analog input terminal A2 using H3-10 and for multi-function analog input terminal A3 using H3-06. · The torque limit accuracy is ±5% at the output frequency of 10 Hz or above. When output frequency is less than 10 Hz, accuracy is lowered. Preventing Motor Stalling During Operation Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter's output frequency when a transient overload occurs while the motor is operating at a constant speed.
