1113
Input of torque constant as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102). The torque
constant is the quotient of rated torque : rated current (RMS) for permanent-field synchronous
motors.
1114
Input of voltage constant as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102). The voltage
constant is measured as an induced voltage (EMF) under no-load conditions at n = 1000
rev/min as the RMS value of the motor terminals (line-to-line).
1115
Input of ohmic resistance of the armature winding (phase value) as specified on the motor data
sheet (non-Siemens motor) or automatic parameterization using machine data "Motor code
number" (MD 1102).
1116
Input of armature rotating-field inductance as specified on the motor data sheet (non-Siemens
motor) or automatic parameterization using machine data "Motor code number" (MD 1102).
1117
Input of motor moment of inertia as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102 - in motors
without a holding brake).
