Signal types
The technology module supports the following four signal types:
Note
The pulse width is fixed depending on the maximum pulse frequency set for the respective
channel.
• PTO (Pulse (P) and direction (D)):
One output (P) controls the pulses and one output (D) controls the direction. D is 'high'
(active) when pulses are generated in the negative direction. D is 'low' (inactive) when
pulses are generated in the positive direction.
• PTO (count up (A), count down (B)):
One output (A) outputs pulses for positive directions and another output (B) outputs
pulses for negative directions.
