stopping.
Using this function, vibration can be decreased while stopping.
Manual pulsar input function
By applying manual pulse signals (PA/PB), you can rotate a motor directly.
The input signals can be 90
In addition to the magnification rates above, the PCL6045B contains an integral pulse number
magnification circuit which multiplies by 1x to 32x and a pulse quantity division circuit which is divided by 1
to 2048. Software limit settings can be used, and the PCL stops the output of pulses. It can also feed in
the opposite direction.
Direct input of operation switch
Positive and negative direction terminals (±DR) are provided to drive a motor with an external operation
switch.
These switches turn the motor forward (+) and backward (-).
Out-of-step detection function
This LSI has a deflection counter which can be used to compare command pulses and encoder signals
(EA/EB).
It can be used to detect out-of-step operation and to confirm a position by using a comparator.
Idling pulse output function
This function outputs a preset number of pulses at the self start frequency (FL) before a high-speed start
acceleration operation.
When the initial speed is set higher during the acceleration, this function is effective in preventing out-of-
step operation.
Operation mode
The basic operations of this LSI are: continuous operation, positioning, zero return, linear interpolation,
and circular interpolation. By setting the optional operation mode bits, you can use a variety of operations.
<Examples of the operation modes>
1) Start/stop by command.
2) Continuous operation and positioning operation using PA/PB inputs (manual pulsar).
3) Operate for specified distances or in continuous operation using +DR/-DR signals (drive switch).
4) Zero return operation.
5) Positioning operation using commands.
6) Hardware start of the positioning operation using
7) Change the target position after turning ON the PCS. (Delay control)
input.
Variety of zero return sequences (Homing)
The following patterns can be used.
1) Feeds at low speed and stops when the ORG signal is turned ON
2) Feeds at low speed and stops when an EZ signal is received (after the ORG signal is turned ON).
3) Feeds at low speed, reverses when the ORG signal is turned ON, and stops when an EZ signal is
received.
4) Feeds at low speed and stops when the EL signal is turned ON. (Normal stop)
5) Feeds at low speed, reverses when the EL signal is turned ON, and stops when an EZ signal is
received.
6) Feeds at high speed, decelerates when the SD signal is turned ON, and stops when the ORG signal
is turned ON.
7) Feeds at high speed, decelerates when the ORG signal is turned ON, and stops when an EZ signal is
received.
8) Feeds at high speed, decelerates and stops after the ORG signal is turned ON. Then, it reverse feeds
and stops when an EZ signal is received.
9) Feeds at high speed, decelerates and stops by memorizing the position when the ORG signal is
turned ON, and stops at the memorized position.
10) Feeds at high speed, decelerates to the position stored in memory when an EZ signal is received
after the ORG signal is turned ON. Then, returns to the memorized position if an overrun occurs.
