Built-in Outputs
Section 6-2
With the CJ1M CPU Unit, it is possible to execute a pulse control instruction
during acceleration/deceleration or execute a positioning instruction to over-
ride another positioning instruction that is in progress.
Note
1.
SPED(885) (Ind.) to SPED(885) (Ind.)
• The number of output pulses cannot be changed.
• The frequency can be changed.
• The output mode and direction cannot be switched.
2.
SPED(885) (Cont.) to SPED(885) (Cont.)
• The frequency can be changed.
• The output mode and direction cannot be switched.
3.
SPED(885) (Ind.) to ACC(888) (Ind.)
• The number of output pulses cannot be changed.
• The frequency can be changed.
• The acceleration/deceleration rate can be changed.
• The output mode and direction cannot be switched.
4.
ACC(888) (Ind.) to ACC(888) (Ind.) or PLS2(887) to ACC(888) (Ind.)
• The number of output pulses cannot be changed.
• The frequency can be changed.
• The acceleration/deceleration rate can be changed (even during acceler-
ation or deceleration.)
• The output mode and direction cannot be switched.
5.
SPED(885) (Cont.) to ACC(888) (Cont.) or ACC(888) (Cont.) to ACC(888)
