The motor and encoder data are saved as an electronic type plate in a motor equipped with
a DRIVE-CLiQ connection. This data is transferred to the Control Unit when commissioning.
As a consequence, when commissioning this motor type, all of the necessary parameters
are pre-assigned and set automatically. The same is true for the parameters required to
monitor the motor temperature. Other changes are not required.
The default settings for monitoring the motor temperature are:
● p0600 = 1, motor temperature sensor for monitoring via encoder 1
● p0601 = 2, the motor temperature sensor type is a KTY84.
● p0604[0...n] motor temperature alarm threshold
● p0605[0...n] motor temperature fault threshold
● p0606[0...n] motor temperature timer (timer to changeover from an alarm to a fault value).
Temperature sensor evaluation
Temperature sensing using PT1000 or KTY84
● When the alarm threshold p0604 is exceeded, alarm A07910 is output.
For vector control, using parameter p0610, you can set the drive response when the
alarm is initiated:
– 0: No response, alarm only A07910, no reduction of I_max
– 1: Alarm A07910 and fault F07011, reduction of I_max
– 2: Alarm A07910 and fault F07011, no reduction of I_max
– 12: Alarm (A07910) and fault (F07011), no reduction of I_max, temperature saved
● When the fault threshold is reached (set via p0605, factory setting = 145 °C), fault
F07011 is triggered in conjunction with the setting in p0610.
Temperature measurement via PTC
● Alarm A07910 is triggered once the PTC responds
● Fault F07011 is triggered once the waiting time defined in p0606 has elapsed
