r0034 CO: Motor utilization / Motor utilization
SERVO_S110-CAN, Can be changed: -
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Displays, signals
Not for motor type: ASM, REL, FEM
Min
- [%]
Description: Displays the motor utilization from the thermal I2t motor model.
Dependency: The motor utilization is only determined for permanent-magnet synchronous motors and if the I2t motor model is
activated.
The motor utilization is formed from the ratio between the I2t motor model temperature (minus 40 Kelvin) and the
reference value p0605 (motor overtemperature, fault threshold) - 40 Kelvin. If p0605 is reduced, r0034 increases
and the motor temperature remains the same.
Refer to: p0611, p0612, p0615
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
A value of r0034 = -200.0 % indicates an invalid display, for example, because the thermal I2t motor model was not
activated or was incorrectly parameterized.
r0035 CO: Motor temperature / Mot temp
SERVO_S110-CAN, Can be changed: -
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Displays, signals
Not for motor type: -
Min
- [°C]
Description: Displays the actual temperature in the motor.
Note: For r0035 not equal to -200.0 °C, the following applies:
- this temperature display is valid.
- a KTY sensor is connected.
- the thermal model for the induction motor is activated (p0612 bit 1 = 1 and temperature sensor de-activated:
p0600 = 0 or p0601 = 0).
For r0035 equal to -200.0 °C, the following applies:
- this temperature display is not valid (temperature sensor error).
- A PTC sensor or bimetallic NC contact is connected.
- the temperature sensor of the synchronous motor is de-activated (p0600 = 0 or p0601 = 0).
r0036 CO: Power unit overload I2t / PU overload I2t
SERVO_S110-CAN, Can be changed: -
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Displays, signals
Not for motor type: -
Min
- [%]
Description: Displays the power unit overload determined using the I2t calculation.
A current reference value is defined for the I2t monitoring of the power unit. It represents the current that can be
conducted by the power unit without any influence of the switching losses (e.g. the continuously permissible current
of the capacitors, inductances, busbars, etc.).
If the I2t reference current of the power unit is not exceeded, then an overload (0 %) is not displayed.
In the other case, the degree of thermal overload is calculated, whereby 100% results in a trip.
Dependency: Refer to: p0290, p0294
