107.39 Encoder gear gain
High byte: Numerator of the gear (1 ... 255)
Low byte: Denominator of the gear (1 ... 255)
If the value is 0x0101, there is no gearing between the motor shaft and the encoder.
The value 0 is not defined and can be returned as an error message
or treated internally like the value 0x0101 (no gearing, hence 1:1 transmission).
107.40 Brake nominal voltage
Voltage for the motor brake. The value displayed is read from motors with an electronic
identification plate and is for information only.
107.41 Brake torque
Holding torque of the motor brake. The value displayed is read from motors with an elec-
tronic identification plate and is for information only.
107.42 Inertia of brake
Moment of inertia of the motor brake. The value displayed is read from motors with an
electronic identification plate and is for information only.
107.43 Nominal torque
Display of nominal torque (at motor nominal temperature, i.e. motor warm); calculated
from nominal output and nominal speed.
107.44 Kt factor
Display motor torque constant in Nm/A.
The connection between torque-generating current and motor torque at the measuring
point (i.e. magnetic flux = 100% and at the nominal temperature "warm" motor).
The Kt factor is calculated from the nominal torque M
nom
(Z107.43–) and nominal torque
current l
sq-nom
(Z19.10–) of the motor.
