Note: Max. permissible actual speed for synchronous motors: Minimum from 1.1 (1.05 from SW 7.1 with ”SIMODRIVE 611 universal HR”, resolver) x P1400 and P1147 Max. permissible actual speed for induction motors: Minimum from P1146 and P1147 refer to the index entry ”Ramp–function generator”. 1257:8 Ramp–function generator ramp–down time MinStandardMaxUnitData typeEffective 0.02.0600.0sFloating Pointimmed.(ARM) 0.00.0600.0sFloating Pointimmed.(SRM SLM) During ramp–down, the setpoint is reduced from the maximum permissible actual speed to zero. Note: Max. permissible actual speed for synchronous motors: Minimum from 1.1 (1.05 from SW 7.1 with ”SIMODRIVE 611 universal HR”, resolver) x P1400 and P1147 Max. permissible actual speed for induction motors: Minimum from P1146 and P1147 refer to the index entry ”Ramp–function generator”. 1259 Torque/power reduction mot./gen. (ARM SRM)(–> 4.1) Force/power reduction mot./gen. (SLM) MinStandardMaxUnitData typeEffective 003HexUnsigned16immed. . defines if the torque/power de–rating or force/power de–rating depends on whether the drive is motoring/generating. Bit 0Torque / power reduction, only when motoring Bit 0 = 1Reduction is only effective when motoring Bit 0 = 0Reduction is effective when motoring and regenerating Bit 1Limiting, motoring/regenerating dependent on Nset Bit 1 = 1The torque limits when motoring are used if the product of torque and speed set- point is positive and the speed setpoint is not equal to 0 Bit 1 = 0The torque limits when motoring are used if the product of torque and speed actual value is positive or the absolute speed actual value is less than 10 RPM Note: Refer under index entry ”Torque/power reduction” 1262 i2t time in limiting MinStandardMaxUnitData typeEffective –––sFloating PointRO . for the i2t power section limit, this is used to display the time during which the power section is being limited. Note: The parameter is reset for value overflow and for POWER ON. refer to the index entry ”i2t power section limiting” A Lists03.0107.03 |
