Description
| This setting is for the maximum permissible voltage for the motor. For instance, if a motor that is rated for a 400V supply is connected to the amplifier, then the setting must be VBUSBAL = 1 (400V). This sets regen and overvoltage thresholds in the amplifier to acceptable values for the motor. This ensures that the motor windings are not damaged. If several amplifiers are connected to the supply with the DC-buses in parallel, then they must all have the same value for VBUSBAL. It must therefore be set to suit the motor with the lowest voltage rating. VBUSBAL=0 (230 V) VBUSMAX=450V VBUSBAL=1 (400 V) VBUSMAX=800V VBUSBAL=2 (480 V) VBUSMAX=900V The setting for the drive 40xM is limited to 0 (230V). The default setting is also 0. The setting for the drive 44xM is limited to 0 (400V). The default setting is also 1. VBUSBAL also changes DICONT and DIPEAK at following drive types (starting with firmware 4.94): VBUSBAL = 0 443 DICONT = 3 DIPEAK = 9 446 DICONT = 6 DIPEAK = 12 VBUSBAL = 1 443 DICONT = 2 DIPEAK = 6 446 DICONT =4 DIPEAK = 8 VBUSBAL = 2 443 not possible 446 not possible |
