6 -20The following only applies to Inverters with SPEC: E or later.The operation after starting or stopping depends on the setting of b1-05 when flux vector control is selected(A1-02 = 3).Fig 6.16 Deceleration to Stop (for Flux Vector Control)Setting Precautions• When using flux vector control, the zero-speed control starts when motor speed drops to b2-01 duringdeceleration. Also, the setting b2-01 < E1-09 is possible.• The current level during injection brake time at start is the value of E2-03 (motor no-load current). Accord-ingly, b2-02 is invalid in flux vector control.Injection braketime at startb2-03Zero-speedcontrolb2-04Baseblockb2-03 b2-04b2-03 b2-04b2-03 b2-04Run Command OFF ON OFFFrequency referencevia analog input0E1-09b1-05=0(frequency reference)Run Command turns OFFand zero-speed control startswhen motor speed drops to b2-01.b1-05=1(Coast)b1-05=2(Run on E1-09)b1-05=3(Zero-speed)Injection braketime at startInjection braketime at startInjection braketime at startBaseblockBaseblockBaseblock BaseblockBaseblockBaseblockBaseblockZero-speedcontrolZero speed controlZero-speed controlFrequency reference drops to lessthan E1-09 and zero-speed controlstarts when motor speed drops tob2-01.Run Command turns OFFand zero-speed control startswhen motor speed drops to b2-01.Run Command turns OFFand zero-speed control startswhen motor speed drops to b2-01.
