3.3 Pulse Train Control Mode (for Pulse Train Type)
This controller can switch over the mode between positioner mode and pulse train control
mode with the parameters. In Pulse Train Mode, there are 2 types, incremental type for
actuator (PIO Pattern 6) and (Battery-less) absolute type for actuator (PIO Pattern 7), the
actuator can be operated by the pulse train output of the host controller (PLC) positioning
control function. This operation mode is not to be changed after the system is complete to be
established or during an operation.
Caution: • In Pulse Train Control Mode, the operation is performed corresponding to the
input pulse.
Input Pulse Value ⇒ Moving distance
Input pulse frequency ⇒ Velocity
Change in Input Pulse Frequency
⇒
Velocity change and acceleration/deceleration
Do not use the actuator above the specifications for the commands of the
movement amount, acceleration and deceleration from the host controller (PLC).
Doing so may cause an abnormal noise or malfunction.
The pressing operation velocity should be set to the rated pressing velocity
described in “10.6 List of Specifications of Connectable Actuators” when it is to
conduct the pressing operation. Pressing with velocity not at the rated pressing
velocity could end up with pressing force different from that shown in “Push Force
and Current-Limiting Value” in Appendix in Chapter 10. Also, operation in velocity
higher than the rated pressing velocity could cause an error or malfunction.
Main Functions
Function Name Name
1
Dedicated home return signal
When this function (signal) is used, home return can be
performed without using a complex sequence or an external
sensor, etc.
2
Brake control function
Since the controller controls the brake, there is no need to
program a separate sequence.
The electromagnetic brake power is supplied to the controller
from a power supply different from the main power.
Accordingly, the electromagnetic brake can be released freely
after the main power has been cut off.
3
Torque limiting function
The torque can be limited (a desired limit can be set by a
parameter) using an external signal. When the torque reaches
the specified level, a signal will be output. This function
(signal) permits pressing and press fitting operations.
4
Position-command primary
filter function
Soft start and stop can be achieved even when the actuator is
operated in the command-pulse input mode where
acceleration and deceleration are not considered.
5
Resistration of datum position
PIO Pattern 7 : Dedicated for
absolute type
Operation is available with the datum position set up at any
position in the movable range of the actuator.
