Temperature measurement
● p0600[0...n] = 20 or 21 activates the motor temperature sensing via an external sensor.
● p0601[0...n] = 11 sets the evaluation for several temperature channels.
● p0608[0...3] allocates the temperature channels for the motor temperatures to signal
● p0609[0...3] allocates the temperature channels for the motor temperatures to signal
● p4100[0...n] = 0 deactivates temperature evaluation.
● r4101[0...3] indicates the actual resistance value of the respective temperature sensor.
● p4102[0/2/4/6] sets the alarm thresholds of the temperature sensors to between -48° C
● p4102[1/3/5/7] sets the fault thresholds of the temperature sensors to between -48° C
● p4102[0...7] = 251° C deactivates the alarm and/or fault message that has been set.
● p4610[0...n] to p4613[0...n], assigns up to four temperature sensors to the motor and
● r4620[0...3] ≠ -200° C means:
● r4620[0...3] = -200° C means:
KTY84
● p4100[0...3] = 2 assigns the temperature sensor type KTY84 to a corresponding channel
● r4105[0...3] displays the actual temperature value of the measuring channel involved of
