? the value defined under "Increments per
revolution"
? the value defined under "Reference
speed"
The low limit of the value range is:
? for the signal type "PTO (A, B phaseshifted
- quadruple)": 0.1 Hz * 60 s/min *
4) / Increments per revolution
? for the non-quadruple PTO signal types:
(0.1 Hz * 60 s/min) / Increments per revolution
The high limit of the value range is the minimum
of the value:
? 2 * reference speed
and of the value:
? for the signal type "PTO (A, B phaseshifted
- quadruple)": (100 000 Hz *
60 s/min * 4) / Increments per revolution
? for the non-quadruple PTO signal types:
(100 000 Hz * 60 s/min) / Increments per
revolution

Increments per
revolution
The "Increments per revolution"
is used to define
the number of increments
per revolution (also in
microstep mode), which is
required by the drive for a
revolution.he PTO channel reacts to a change to CPU STOP by removing the drive enable (if the
drive enable output is configured) and outputting the velocity setpoint 0 at the hardware
outputs configured for the signal tracks A and B. The CPU STOP reaction of the PTO
channels cannot be configured.
Note
Reaction to CPU STOP
Upon CPU STOP, the hardware outputs assigned for the PTO outputs A and B can switch to
signal state 'High' (1) and/or remain there. It is not guaranteed that the two hardware outputs
switch to/remain in signal level 'Low' (0).The pulse output channels for the four modes of the pulse generators (PTO) are controlled
using Motion Control via the technology objects TO_SpeedAxis, TO_PositioningAxis and
TO_SynchronousAxis. With these operating modes, the control and feedback interface of the
channels is a partial implementation of the PROFIdrive interface "Telegram 3". For a detailed
descrtion of the use of motion control and its configuration, refer to the Motion The function "High-speed output (0.1 A)" improves the signal clock of the digital outputs
(DQ0 to DQ7). Less delay, fluctuation, jitter, and shorter rise and fall times occur at the
switching edges.
The function "High-speed output (0.1 A)" is suitable for generating pulse signals in a more
precise clock, but provides a lower maximum load current.
For the PWM and Frequency output modes, select the high-speed output of the channel in
STEP 7 (TIA Portal). You can also change the parameter assignment during runtime with the
help of the program via the data record.
High-speed pulse output (high-speed output) is available for the following operating modes:
● PWM
● Frequency output
● PTO (the pulse outputs for the PTO mode are always "High-speed output (0.1 A)")A lower value is theoretically possible but, depending on the connected load, the output voltage can no longer be output
as complete rectangular pulse
2) Load-dependentIn the modes "Pulse width modulation PWM" and "Frequency output", you can set the pulse
output (DQA) of a pulse generator directly via the control program. Select the function for the
DQ direct control by deleting the output control bit of the PWM channel (TM_CTRL_DQ = 0)
in the control interface.
The direct control of the pulse output (DQA) can be helpful when commissioning a control
system for automation.
