Actual signals and parameters 217 All parameters No. Name/Value COMM EXT2 DI1(INV) DI2(INV) Description Def/FbEq Fieldbus interface as the source for the torque limit 1/2 7 selection, ie control word 0301 FB CMD WORD 1 bit 15. The control word is sent by the fieldbus controller through the fieldbus adapter or embedded fieldbus (Modbus) to the drive. For the control word bits, see section DCU communication profile on page 320. Maximum torque limit 1 is defined by parameter 2017 MAX TORQUE 1 and maximum torque limit 2 is defined by parameter 2018 MAX TORQUE 2. Note: This setting applies only for the DCU profile. Value of signal 0112 EXTERNAL REF 2 11 Inverted digital input DI1. 1 = parameter 2017 MAX TORQUE 1 value. 0 = parameter 2018 MAX TORQUE 2 value. See selection DI1(INV). DI3(INV) DI4(INV) DI5(INV) 2015 MIN TORQUE 1 See selection DI1(INV). See selection DI1(INV). See selection DI1(INV). Defines minimum torque limit 1 for the drive. See parameter 2013 MIN TORQUE SEL. -600.0…0.0% Value in percent of the motor nominal torque 2016 MIN TORQUE Defines minimum torque limit 2 for the drive. See parameter 2 2013 MIN TORQUE SEL. -600.0…0.0% Value in percent of the motor nominal torque 2017 MAX TORQUE Defines maximum torque limit 1 for the drive. See 1 parameter 2014 MAX TORQUE SEL. 0.0…600.0% Value in percent of the motor nominal torque 2018 MAX TORQUE Defines maximum torque limit 2 for the drive. See 2 parameter 2014 MAX TORQUE SEL. 0.0…600.0% Value in percent of the motor nominal torque 2020 BRAKE CHOPPER -1 -2 -3 -4 -5 -300% 1 = 0.1% -300% 1 = 0.1% 300% 1 = 0.1% 300% 1 = 0.1% Selects the brake chopper control. INBUILT INBUILT When using the drive in a Common DC bus system, the parameter must be set to EXTERNAL. When in Common DC, the drive cannot feed or receive more power than PN. Internal brake chopper control. 0 EXTERNAL Note: Ensure the brake resistor(s) is installed and the overvoltage control is switched off by setting parameter 2005 OVERVOLT CTRL to selection DISABLE. External brake chopper control. 1 Note: The drive is compatible only with ABB ACS-BRK-X brake units. Note: Ensure the brake unit is installed and the overvoltage control is switched off by setting parameter 2005 OVERVOLT CTRL to selection DISABLE.
