11.3 Precautions on Programming

■
Common precautions to each operation
● If the values for the startup speed, target speed, acceleration / deceleration, or position
command value exceed the range of values which can be specified, a function block error
will occur, and operation cannot be initiated.
● With the GM1 pulse output unit, specify the speed (startup speed and target speed) in the
unit of "u/s". 1 u/s = 1 pps
■
Precautions on programming (Pulser input operation function)
● When counting the 2-phase input such as the input from the encoder, specify the parameter
to set the pulse input transfer multiple to "4 multiple setting" (x 4) or "2 multiple setting" (x 2)
to prevent counting error.
● Set the target speed to a moderately large value according to the pulse output transfer
multiple during pulser input operation. If the pulse output transfer multiple is large and the
target speed is small, the command for the next pulser input may be executed before
completing the pulse output for the specified number of pulses, and the output for the
number of input pulses may not be obtained.
● Do not execute PG_Pulser for using the feedback counter function.
