VACON® 3000
Application Guide
The Filter Time Constant frequency must not be too large. A too large constant has a negative effect on speed control performance.
Values higher than 10 ms are usually too large.
7.342 (ID 3044) Frequency Monitor B Timeout
Location in the menu: P3.15.5.14
Use this parameter to set the integral time limit for the error excursion of the encoder frequency. Give the limit in ms.
7.343 (ID 3045) Frequency Monitor B Response
Location in the menu: P3.15.5.15
Use this parameter to set the response to an encoder failure:
• 0 = Give a fault
• 1 = Fall back to a secondary encoder
• 2 = Fall back to sensorless operation
7.344 (ID 3301) Modulator Options
Location in the menu:
• INU application: P3.1.2.6.3
• AFE application: P3.2.7.3
Use this parameter to select the modulator options:
• Deadtime compensation.
• Switching frequency reduction at start.
7.345 (ID 3302) Synchronous Modulation
Location in the menu:
• INU application: P3.1.2.6.4
• AFE application: P3.2.7.4
Use this parameter to set the synchronous modulation type:
• Asynchronous.
• Symmetric synchronous.
• Synchronous
• Soft synchronous.
7.346 (ID 3303) Fsw Reduction Min
Location in the menu: P3.1.2.6.6
Use this parameter to set the minimum switching frequency reduction level in kHz.
7.347 (ID 3304) HS Cap Vrms Enable
Location in the menu:
•
AFE application: P3.8.1.10
Use this parameter to set the V
7.348 (ID 3305) DC-Link Compensation TC
Location in the menu: P3.1.2.6.7
Use this parameter to select the time constant specification for the low-pass filter that is used to slow down the DC-link voltage
compensation.
0 = Disable the low-pass filter.
7.349 (ID 3306) PHM Temperature Sensor Disable
Location in the menu:
