Multi-Step Position Switching Function (Cp1/Cp2/Cp3) - Omron 3G3MX2 User Manual

The trigger for starting deceleration according to the speed reference is as follows:
Number of pulses required for (the number of rotations equivalent to the triangle for
deceleration from the current frequency at the applicable deceleration time + 1.25 rotations) <
Position deviation
If movement decelerates to the creep speed before the following stopping condition is met,
movement continues at the creep speed. Movement stops using DC injection braking when the
position deviation becomes less than 50 pulses (calculated at x4).
If the position command is set to a low value, the Inverter may conduct deceleration and
perform positioning before the speed command value is reached. If the position command is
"0," DC injection braking (DB) is applied immediately when the RUN command is turned ON.
The position at power-on is recognized as the zero (position = 0). (When the power is turned
off, the current value is cleared.)
If the current position counter exceeds the specified position range, a Position Control Range
Trip (E83) occurs and the Inverter runs freely. If the PCLR terminal is allocated, turning ON the
PCLR terminal clears the current position counter. (The internal position deviation counter is
cleared simultaneously.)
In Reset Selection (C102), select "03: Trip reset only."
If Reset Selection (C102) is not set to 03, turning ON the Inverter's reset terminal (STOP/RESET
key) clears the current position counter. To operate the Inverter by using the current position
count value after resetting a trip by turning ON the reset terminal (STOP/RESET key), be sure to
set Reset Selection (C102) to 03.
Reference
In the simple position control mode, the direction of RUN command (FW, RV) does not indicate the
rotation direction. The FW or RV signal starts or stops the Inverter. The Inverter runs forward when
"Target position - Current position" is a positive value, or runs in reverse when it is a negative value.
In the simple position control mode, the ATR terminal is disabled.(Torque control is disabled.)

Multi-step Position Switching Function (CP1/CP2/CP3)

Selection of multi-step positions 0 to 7 becomes possible when "66: CP1" to "68: CP3" are
allocated to Multi-function Input Selections (C001 to C007).
Set position commands in Multi-step Position Commands 0 to 7 (P060 to P067). (The unit is
based on poool setting. This is not dependent on whether a single-phase or dual-phase
encoder input is used and no need consider for x4 operation.)
If no position command is allocated to the terminals, Multi-step Position Command 0 (P060) is
defined as the position command.
