istance. The direction can also be specified by using two signals per channel. You can use
a PTO channel for setpoint output (drive) for an axis technology object.
PTO mode is divided into the following four signal types:
● PTO (pulse (A) and direction (B)): If you select the PTO signal type (pulse (A) and
direction (B)), an output (A) controls the pulses and an output (B) controls the direction. B
is 'High' (active) when pulses are generated in a negative direction. B is 'Low' (inactive)
when pulses are generated in a positive direction.
① Positive direction of rotation
② Negative direction of rotation
● PTO (Count Up (A) and Count Down (B)): When you select PTO when you select the
PTO signal type (count up (A) and count down (B)), an output (A) outputs pulses for
positive directions and another output (B) outputs pulses for negative directions.PTO (A, B phase-shifted): When you select the PTO signal type (A, B phase-shifted), the
two outputs pulses with the specified velocity, but phase-shifted by 90 degrees. This is a
1x combination in which the pulse shows the duration between two positive transitions of
A. In this case the direction is determined based on the output which first changes from 0
to 1. With positive direction, A preceeds B. With negative direction B preceeds A.
The number of generated pulses is based on the number of 0-to-1 transitions from phase
A. The phase ratio determines the direction of motion:
PTO (A, B phase-shifted - quadruple): When you select the PTO signal type (A, B phaseshifted,
quadruple), the two outputs transmit pulses with the specified velocity, but phaseshifted
by 90 degrees. The quadruple signal type is a 4x configuration in which each edge
transition corresponds to an increment. Therefore, a full period of the signal A contains
four increments. In this way two outputs, each with 100 kHz signal frequency, can be
used to output a control signal that supplies 400,000 increments per second. The
direction is determined based on the output which first changes from 0 to 1. With positive
direction, A preceeds B. With negative direction B preceeds AWith the parameter "No

Reference speed With the parameter
"Reference speed" you
define the reference
value for the drive velocity.
The drive velocity
is defined as percentage
value of the reference
speed in the
range from -200 % to
+200 %.
Floating-point number:
1.0 bis 20,000.0 (rpm)
3,000.0 (rpm)
Maximum speed The parameter "Maximum

define the required
maximum speed for
