Protection circuit
Overvoltage and undervoltage protection
Overtemperature protection (> 75° Celsius on the power board)
Polarity reversal protection: In the event of a polarity reversal, a
short-circuit will occur between supply voltage and GND over a
power diode; a line protection device (fuse) is therefore necessary
in the supply line. The values of the fuse are dependent on the
application and must be dimensioned
●
greater than the maximum current consumption of the controller
●
less than the maximum current of the voltage supply.
If the fuse value is very close to the maximum current consumption
of the controller, a medium / slow tripping characteristics should be
used.
3.4 Overtemperature protection
Above a temperature of approx. 75°C on the power board (corresponds to 65–72°C outside on the back
cover), the power part of the controller switches off and the error bit is set (see objects 1001
h
and 1003
h
).
After cooling down and confirming the error (see table for the controlword, "Fault reset"), the controller again
functions normally.
The following temperature test results provide information on the temperature behavior of the motor.
Temperature tests are performed under the following conditions:
●
Operating voltage: 24 V DC (BLDC motor PD4-CB)/48 V DC (stepper motor PD4-C)
●
Motor current: 4.2 A (stepper motor PD4-C)/8 A (BLDC motor PD4-CB) rms
●
Operation mode: Velocity Mode, full step, 30 rpm, open loop
●
Ambient temperature: 25 °C / 45 °C
●
Altitude of site: 500 m above sea level
●
No external cooling in the climatic chamber, e.g., via fan
