P116* This parameter defines the transmission ratio between the
1FW3 ratio motor and the encoder in the case of 1FW3 torque
motors.
116 The transmission ratio is indicated as a quotient.
Index 1 defines the revolutions of the motor shaft
(numerator) during simultaneous revolutions of the
encoder shaft in Index 2 (denominator).
Transmission ratio =
The absolute value of P116.01 must be less or equal to
the absolute value of P116.02. Moreover, the number of
motor pole pairs (P109) has to be an integer multiple of
the value of P116.02. If one of these two conditions is not
satisfied, fault F061 with fault value 116 is set upon exiting
the drive settings.
P117 Corner points for describing the linear adaption of the gain
Kp-Adapt. factor Kp of the current controller as a function of the
curve of the inductivity of the synchronous machine.
117
Index 1: Value of current at which the linear reduction
begins (up to which the inductivity has the value of P120.1)
Index 2: Value of current at which the linear reduction
ends (from which the inductivity has the value of P120.2)
P119* Function parameter for entering the ratio of
Ratio Lq/Ld the mutual inductance transversal to the rotor-axis (Lq)
to the mutual inductance along the rotor-axis (Ld)
119 of a connected synchronous motor.
The parameter value is calculated during the automatic
motor data identification of derived motor data (P115).
P120* Function parameter for entering the main field inductance
Main Field Induc (in mH) of a connected synchronous motor. The value to
be entered is 1.5 times the inductance of a winding phase
120 in the star equivalent circuit.
P121* Function parameter for entering the stator resistance of a
Stator Resist connected synchronous or induction motor. The value to
be entered corresponds to the ohmic resistance of a
121 winding phase at 20°C.
P122* Function parameter for entering the total leakage
Tot Leak React reactance of a connected induction motor. The value to be
entered corresponds to the total leakage reactance of a
122 winding phase. The parameter value is calculated during
the automatic calculation of derived motor data (P115).
