8. Operation methods
8.1 Outline
Two types of operation method are available for this product on the EtherCAT network. The first method
is “Operation by Step No.”. When using this method, step data stored in the product can be driven by
sending specific commands over the network. The second method is “Operation by numerical
instruction”. When using this method the numerical data (e.g. Position, speed etc.) is changed based on
the already set step data.
8.2 Operation by Step No.
Instructions and monitoring of the movement of the actuator are possible by reading/writing the memory
bits corresponding to the input/output port signals (e.g. DRIVE, INP) using a master (PLC).
When an operation is based on the preset step data, select the step data No. then activate the DRIVE
signal.
Refer to
13.2 Operation procedure for Operation by Step No. (P.49)
.
8.3 Position/speed monitor
Reads the current position and current speed for monitoring.
Refer to
9. Memory map (P.29)
for the current position and speed.
8.4 Operation by numerical instruction
When numerical data relating to the actuator speed, position etc. is sent, the actuator will execute this
data provided it is within the allowable range of values.
For the JXCEH controller, it is possible to instruct all step data items (operation method, speed, position,
acceleration, deceleration, pushing force, switch point, pushing speed, positioning thrust, area 1, area 2,
positioning width) by numeric values.
Preparatory operations such as turning the servo on and performing a return to origin are required
before the actuator may execute numerical data.
Refer to
13.3 Operation procedure for operation by numerical instruction (P.54)
