Table 4.4: Connecting a TMCM-035 to a TMCM-100 (analog)
Please see section 4.4 for selecting the peak motor current.
In analog mode the LED shows the status of the module:
The LED is on when the motor is enabled and the supply voltage is high enough.
The LED is off when the motor is disabled due to pin 11 (Enable) set high or supply voltage to
low.
The LED flashes when there is an error :
Temperature too high: motor stops until temperature is acceptable (normally a few seconds)
Current too high (short circuit): motor is switched off until short circuit is corrected
Power supply too low for motor: motor is switched off, until power supply is sufficient.
Open load: motor is NOT switched off (occurs when a motor coil circuit is open or sometimes
at high velocities when the motors current limit is reached
