Sequential Operation

Sequential Operation

The sequential operation can be performed by setting 16.Pr52 (sequential operation setting) to “1”. When the sequential operation is set, execute a step operation by incrementing a point number by 1 at every inputting the strobe signal input (STB: CN X5 Pin 24) when the servo turns on, not using the point specifying input (P1IN to P32IN: CN X5 Pin 3, 4, 5, 6, 7 and 8).

• Homing operation at sequential operation

1)16.Pr38 (homing disabling setting) is “0” (homing required) and an operation mode is not the absolute mode (SV.Pr0B (absolute encoder setting) is “1”).

=> Homing is executed by the first strobe signal input (STB) after the power supply turns on. A sequential operation is performed beginning with the point 1 after the next strobe signal.

2)16.Pr38 (homing disabling setting) is “1” (homing not required) and an operation mode is the absolute mode (SV.Pr0B (absolute encoder setting) is “0” or “2”).

=> A sequential operation is performed beginning with the point 1 when the first strobe signal is input, because homing is not required.

A maximum point number of the sequential operation can be set by 16.Pr53 (a maximum point number of sequential operation). After a step operation of the maximum point number is executed, the operation re- turns to the point 1. In the sequential operation, the maximum point number can be specified in a range between 1 and 60, because the setting of SV.Pr57 (selection of number of input points) is disabled.

Example of Operation

16.Pr52 (sequential operation setting) = 1 (enabled)

Caution

1)When setting the sequential operation, an operation command (step operation, homing, jog operation or Alarm Clear) cannot be executed by the point specifying input (P1IN to P32IN). However, the Alarm Clear can be specified by assignment of the multifunction input 1/2 (EX-IN1/EX-IN2: CN X5 Pin 22/25).

2)A block operation is unavailable when the sequential operation is set.
