5.2.13 overtemperature shut-off
When overtemperature is detected, all half bridge outputs will be turned into tristate, and the Data Ready flag is
set (output DRB goes low). As an indication, the overtemperature bit of byte no. 2 in hardware error mode is set
to 1
5.2.14 over/Undervoltage shut-off
In case of overvoltage or undervoltage a moving motor is stopped, the currently counted number of ripples is
stored, and the DRB flag is set. Outputs in half bridge control mode switch on again automatically after the power
supply has gone back into normal operating range. No diagnostic information will be generated.
5.2.15 open load Detection
Open load detection in motor control mode is performed by the internal current threshold IMOT,GT7P in combina-
tion with the stall detection. When the half bridges to drive the motor are turned on, but no ripple pulses are de-
tected for 200ms, this usually means that the motor is stalled. Motor current thus should be stall current. If in this
case the motor current is lower than IMOT,GT7P threshold mentioned above, the interpretation is "Open Load".
5.2.16 output Drb, acknowledge of positioning and Diagnostic Data
The Data Ready Output pin DRB goes low whenever a required motor position is reached or diagnostic data is avail-
able. DRB is reset after the complete set of data has been transmitted via TXD, simultaneously with a valid data
telegram received at the input RXD.
There are several conditions under which it is not possible to transmit data completely:
Positioning data of more than 1 motor is available
Positioning data is available, but received data telegram is only 1 byte long (Bit 10 is 0
New data has become valid after CSB has gone low and transmission has started
Received data telegram has been detected to be corrupted.
One or more of the configuration registers is badly/not initialised or corrupted.
In any of these cases DRB stays active (low) until data is completely transferred.

Description
Origin of the configuration data: Upon each readout of this configuration regis-
ter no.2 there is an increment of the motor select bits.
If there was a writing to a motor controller, the readout address is set to this
motor controller register.
If there was a writing to motor controller 0 (writing to all motor controllers) the
readout adress is set to 0, too. This indicates that all motor controller have the
same setting for configuration register 2.
