Application Procedure for Inverter Positioning
■
Positioning Instruction Settings
• PULSE OUTPUT (PLS2)
Port: Inverter positioning, Mode: Absolute pulse
• SET PULSES (PULS)
Port: Inverter positioning, Mode: Absolute pulse
+ SPEED OUTPUT (SPED)
Mode: Independent
• SET PULSES (PULS)
Port: Inverter positioning, Mode: Absolute pulse
+ ACCELERATION CONTROL (ACC)
Port: Inverter positioning, Mode: Independent
Determine positioning
patterns.
Decided to use error counter 0 or 1.
Determine inverter specifications
Wire the system.
Set inverter parameters.
Set PLC Setup.
Write ladder program.
Determine applicability.
Determine instructions to use.
· PLS2
· PULS + SPED
· PULS + ACC
· Etc.
For example, the control method (V/f control
or vector control)
· RS-485 communications (Modbus-RTU)
· Analog signal
· Enable inverter positioning
Error counter calculation cycle
Gain
In-position width
Minimum output
Error counter error setting
Power supply frequency per motor rotations/s
Number of encoder pulses per motor rotation
· High-speed counter
Counting mode
Numeric range mode
Etc.
· Enter positioning instructions.
· Program scaling for inverter frequency commands.
· Program forward/reverse operation instructions, stopping instructions,
etc.
Determine inverter command
method.
