Option
Function
Error
The status flag “Error” lights up and the motor will stopped if an error has occurred.
The TMC603 has three different sources for signaling an error:
The TMC603 has three different sources for signaling an error:
1. Undervoltage of the low side supply
2. Undervoltage of the charge pump
3. Short to GND detector
In addition the status flag “Error” lights up if you try to ramp up the motor with sine

Overload
The status flag “Overload” lights up if a current overload is detected. In this case
the PWM duty cycle will be decreased. You can define the current limiting by
setting the parameter “Maximum current”.

Current Control
Here you can configure the current controller. Please take into account the
manufacturer’s data of the used BLDC motor.
manufacturer’s data of the used BLDC motor.
Current Ref.
The current reference value defines the maximum current value for startup.
Current Time
The parameter “Current Time” is the regulation time of the current controller.

Control Kp
Control Kp
The parameter “Current Control Kp” is the proportional gain (Kp) of the controller.
Speed Control
In this field you can modify the speed control parameters.
Speed Ref.
The speed reference value defines the actual motor speed.
Speed Ctl.
Time

If this option is selected the speed control is enabled. You can disable the speed
control by deactivating this option. In this case you can enter the PWM duty cycle
(Duty cycle ref.) by pressing the “Set” button. If you disable the speed control, be
sure that the “Duty Cycle Ref.” is unequal to zero. Otherwise the motor will stop.
Please note if the speed control is disabled, the motor will start without ramp up.
