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 = 2 (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. VBUSBAL - Setting in the range of 40 to 750 are used to choose the maximum network voltage. In this case ist VBUSMAX = 1,2 x VBUSBAL only for S300: VBUSBAL=0 (115 V) VBUSMAX = 235V, regen threshold = 200V only for S300/S700: VBUSBAL=1 (230 V) VBUSMAX = 455V, regen threshold = 400V VBUSBAL=2 (400 V) VBUSMAX = 800V, regen threshold = 720V VBUSBAL=3 (480 V) VBUSMAX = 900V, regen threshold = 840V additional for S748/S772 since FW-version 5.67 VBUSBAL=4 (480V) VBUSMAX = 900V, regen threshold = 790V The default value of VBUSBAL depends on the type of the drive: S303,S306,S310 : VBUSBAL=2 S341,S343,S346 : VBUSBAL=3 S700: 230V version VBUSBAL=1 S700: 400V version VBUSBAL=3 S748/S772: since FW 5.67 VBUSBAL=4 |
