Clock input for rotation direction control
To switch rotation between forward and reverse, there are two types of clock input: one-clock input
and two-clock input.
One-clock input
One clock pin, CK1 or CK2, is used for clock input. In this case, rotation is switched between
forward or reverse using a CW or CCW signal.
<Input signal example: 1-2-phase mode>
Two-clock input
Both clock pins, CK1 and CK2, are used for clock input. Switching between CK1 and CK2 controls
forward and reverse rotation.
<Input signal example: 1-2-phase mode>
