♦ A variety of counter circuits
The following four counters are available separately for each axis.
Counter
Use or purpose
Counter Input/Output
COUNTER1
28-bit counter for control of the command position Outputs pulses
COUNTER2
28-bit counter for mechanical position control
(Can be used as general-purpose counter)
EA/EB input
Outputs pulses
PA/PB input
COUNTER3
16-bit counter for controlling the deviation between
the command position and the machine's current
position
Outputs pulses and EA/EB
input
Outputs pulses and PA/PB
input
EA/EB input and PA/PB
input
COUNTER4
28-bit counter used to output synchronous signals
(Can be used as general-purpose counter)
Outputs pulses
EA/EB input
PA/PB input
1/2 of reference clock
All counters can be reset by writing a command or by providing a CLR signal.
They can also be latched by writing a command, or by providing an LTC or ORG signal.
The PCL6045B can also be set to reset automatically soon after latching these signals.
The COUNTER1, COUNTER2, and COUNTER4 counters have a ring count function that repeats counting
through a specified counting range.
♦ Comparator
There are five comparator circuits for each axis. They can be used to compare target values and internal
counter values.
The counter to compare can be selected from COUNTER1 (command position counter), COUNTER2
(mechanical position counter), COUNTER3 (deflection counter), and COUNTER4 (a general-purpose
counter).
Comparators 1 and 2 can also be used as software limits (+SL, -SL).
♦ Software limit function
You can set software limits using two of the comparator's circuits.
When the mechanical position approaches the software limit range, the LSI will instruct the motors to stop
immediately or to stop by deceleration. After that these axes can only be moved in the direction opposite
their previous travel.
♦ Backlash correction function / Slip correction function
The LSI has a backlash correction function. Each time the feed direction is changed, the LSI applies a
backlash correction. However, the backlash correction cannot be applied while performing a circular
interpolation.
♦ Synchronous signal output function / Slip correction function
Both the backlash and slip corrections are available.
Backlash correction corrects the feed amount each time the feed direction is changed. Slip correction
corrects the feed amount regardless of the feed direction.
♦ Simultaneous start function
Multiple axes controlled by the same LSI, or controlled by multiple sets of this LSI, can be started at the
same time.
♦ Simultaneous stop function
Multiple axes controlled by the same LSI, or controlled by multiple sets of this LSI, can be stopped at the
same time by a command, by an external signal, or by an error stop on any axis.
♦ Vibration restriction function
Specify a control constant in advance and add one pulse each for reverse and forward feed just before
