Connections
IN1: 16 bit integer (15 bit + sign); ramp input
IN2:
16 bit integer (15 bit + sign); ramp up time in ms (related to 20,000), acceleration
IN3:
16 bit integer (15 bit + sign); ramp down time in ms, (related to 20,000), deceleration
OUT: 16 bit integer (15 bit + sign); ramp output
Sqrt
Arithmetical function

Operation
OUT is the square root of IN1 * IN2. With IN3 = true IN1 and IN2 are read as absolute values:
|2|*|1| ININOUT =
With IN3 = false OUT is set to zero if IN1 * IN2 is negati

SqWav
Arithmetical function
Illustration
Operation
OUT alternates between the value of IN3 and zero (0), if the block is enabled with IN1 = true.
The period is set with IN2 in ms.
Connections
IN1: boolean; true = enable SqWav, false = disable SqWav
IN2:
16 bit integer; cycle time in ms
IN3:
16 bit integer (15 bits + sign); height of square wave
OUT: 16 bit integer (15 bits + sign); square wave
