Nm/A
Active on
Power On
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.
Voltage constant

V
Active on
Power On
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).
Armature resistance

V/A
Active on
Power On
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).
Armature inductance
1116
Default value

Active on
Power On
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).
