	Properties
	Control Method
Controls how the motor is controlled. On/Off requires output pins PWM requires a hardware PWM channel H-Bridge requires a hardware H-Bridge channel
	Bridge Type
	Enable Method
Decides how the motor outputs are enabled.
	Channel
PWM Channel selector
	Alt Pin Enable
Alternative Pin Enable (if available on target device)
	Port
	Remap Pin
	Period Register
PWM Period Register value
	Prescaler Divide
Prescaler Divider value
	PWM Timer
Timer associated with PWM to drive the output. Warning - All PWM channels linked to the same timer will share the same period and prescaler settings.
	Frequency (KHz)
	Direction Pin
	Channel
PWM Channel selector
	Polarity
Selects the active output voltage. Active high - Pins will be low when inactive and high when active. Active Low- Pins will be high when inactive and low when active.
	Timer
Timer associated with PWM to drive the output. Warning - All PWM channels linked to the same timer will share the same period and prescaler settings.
	Prescaler Divide
Prescaler Divider value
	Period Register
PWM Period Register value
	A Pin
Output Pin A
	B Pin
Output Pin B
	C Pin
Output Pin C
	D Pin
Output Pin D
	A Remap Pin
Remap Pin A - Specifies the pin used for the A output. Only available on devices supporting remappable hardware pins.
	B Remap Pin
Remap Pin B - Specifies the pin used for the B output. Only available on devices supporting remappable hardware pins.
	C Remap Pin
Remap Pin C - Specifies the pin used for the C output. Only available on devices supporting remappable hardware pins.
	D Remap Pin
Remap Pin D - Specifies the pin used for the D output. Only available on devices supporting remappable hardware pins.
	Frequency (KHz)
Calculated PWM output frequency in KHz.
	Rising Bits
Number of bits assigned to the rising edge dead band counter. Auto populated based on selected target chip.
	Falling Bits
Number of bits assigned to the falling edge dead band counter. Auto populated based on selected target chip.
	Rising Count
Number of cycles to wait after a falling edge and before a rising edge.
	Falling Count
Number of cycles to wait after a rising edge and before a falling edge.
	Speed
Speed of the motor when turned on. Positive speed -> Counter-clockwsie Negative speed -> Clockwise
	Acceleration
Speed change per second when the motor us powered. Set to zero for instantaneous speed changes.
	Deceleration
Speed change per second when the motor is coasting with no power. Set to zero for instantaneous speed changes.
	Show Actuator
When active, an actuator is shown on the motor spindle to make the animation easier to observe.
	Forwards Direction
Which way the motor will rotate when the 'forwards' command is sent.
	Target Object
An object or group to link the motor to - the object will move along with the motor.
	Connections
	PinA
First control pin - set 'pattern' properties below to set the pin's function.
	Forwards Pattern
The state of pins A and B required to drive the motor in a forwards direction.
	Reverse Pattern
States of pins A and B required to drive the motor in a reverse direction.
	Coast Pattern
States of pins A and B required to stop the motor.
	Brake Pattern
States of pins A and B required to stop the motor.
