Functions and Parameters
Lower limit of hysteresis = 15.2 * rated frequency / rated voltage
●
Upper limit of hysteresis = 22.8 * rated frequency / rated voltage
●
For sensorless vector control, the output torque in "high speed area" is limited
by the reference selected by C3.47.
For vector control with encoder, the output torque in both areas are limited by
the reference selected by C3.47.
C3.47 setting range:
C3.47 = 0: Parameter C3.44 and C3.45
●
C3.44 "Torque positive limit" is used to set the limit maximum value of posi-
tive torque of the frequency converter.
C3.45 "Torque negative limit" is used to set the limit minimum value of the
negative torque of the frequency converter.
The reference torque direction will be set by [U0.00] or external terminals:
– If [E0.01] = 0 "Operating panel", the reference torque direction will be set
by [U0.00]. [U0.00] = 0 "Forward" means the reference torque direction is
positive. [U0.00] = 1 "Reverse" means the reference torque direction is
negative.
– If [E0.01] = 1 "Multi-function digital input", the reference torque direction
will be determined according to running direction which is controlled by
external terminals. ("Forward" corresponding to "Positive" and "Reverse"
corresponding to "Negative".
C3.47 = 1: AI1 analog input
●
The range of AI1 corresponds to the 0.0...200.0% rated torque.
C3.47 = 2: AI2 analog input
●
The range of AI2 corresponds to the 0.0...200.0% rated torque.
C3.47 = 3: EAI1 analog input
●
The range of EAI1 corresponds to the 0.0...200.0% rated torque.
C3.47 = 4: Communication
●

C3.47 = 5: EAI2 analog input
●
The range of EAI2 corresponds to the 0.0...200.0% rated torque.
