2 Functional overview
Position control is a control mode in which the motor moves the load to a specified target
position.
The servo driver can be controlled by a pulse train in the frequency range between 1Hz and
8MHz from a host controller such as a PLC or a CNC controller or by block operation. With
block operation, the user defines the positioning parameters in command blocks. The MINAS
A6 servo driver has a block memory capacity of 256 command blocks. All command blocks
are saved in a block operation table in the servo driver.
Block operation table
You can set the command blocks using the PANATERM configuration software or by Modbus
commands if you are using a PLC with a Modbus RTU communication interface. The
command blocks are either started by digital signals (e.g. STB, B-SEL1 to B-SEL128) from a
PLC, a trigger switch, or by Modbus commands.
This Quick Start Guide explains how to wire and configure the servo driver for block
operation using Modbus commands.
Example
An FP0H PLC and a MINAS A6SF servo driver are connected to control the driver by
Modbus commands.
