7.3.2 Drive MD (data description)

Number of pole pairs motor

1112

Default value

Lower input limit

Upper input limit

Units

0

0

4

Active on

Power On

Input of number of pole pairs of motor as specified on the motor data sheet (also non-Siemens
motor) or through automatic parameterization using machine data "Motor code number"
(MD 1102). The pole pair number 0 is entered when motor/power section combinations which
have not been enabled are loaded.

Note:

This data is relevant only for FDD drives.

If these limits are exceeded, the drive outputs an error message.

Torque constant

1113

Default value

Lower input limit

Upper input limit

Units

0.0

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.

Note:

This data is relevant only for FDD drives.

Voltage constant

1114

Default value

Lower input limit

Upper input limit

Units

0.0

0.0

300.0

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).

Note:

This data is relevant only for FDD drives.
