NOTICE
Do not connect or disconnect motor during operation!
Motor cable and mo-
tor inductivity might lead to voltage spikes when the motor is (dis)connected
while energized. These voltage spikes might exceed voltage limits of the driver
MOSFETs and might permanently damage them. Therefore, always switch off
/ disconnect power supply or at least disable driver stage before connecting /
disconnecting motor.
NOTICE
Take care of polarity, wrong polarity can destroy the board!
4.2 STO Input Connector
The TMCM-6214 offers two STO (torque-off) input connectors (2pin JST PH series).

Table 5: STO Connector Pin Assignment
NOTICE
Both STO inputs have to be connected to positive supply voltage (e.g. 24V,
min. 15V) in order to enable all six motor driver stages!
No motor movement
will be possible in case one or both of these inputs are left unconnected.
If both STO inputs are not in the same state for more than 2.3 seconds the module
will lock itself in torque-off mode. This state can only be reset by a power cycle.
4.3 RS485 Connector
The TMCM-6214 offers one RS485 interface connector (3pin JST PH series).
