Product details

4-axis PTP positioning — what the control system means for your motion profile

The QD75P4 runs point-to-point (PTP) positioning over four independent axes — each axis gets its own trajectory planning, so a pick-and-place cycle on axis 1 doesn't stall the conveyor index on axis 2. PTP control means the module handles the acceleration/deceleration ramp between programmed positions without the CPU managing the motion profile mid-stream; the PLC just sends the target coordinate and the QD75P4 executes the move.

Current draw and backplane loading — 0.58 A at 24 VDC

The module draws 0.58 A from the backplane — that's the total current budget for the positioning logic and the pulse-train outputs to the servo drives. A typical MELSEC rack with a Q-series CPU and three or four of these modules stays under the 5 A backplane supply limit, but check the sum against your rack's power module rating.

Flash ROM endurance — 100,000 write cycles for parameter storage

The onboard flash ROM that stores axis parameters and positioning data is rated for 100,000 write cycles — that's the typical endurance for industrial flash used in MELSEC positioning modules. For a machine that gets re-tooled weekly (say 50 parameter saves per year), the flash outlasts the machine's service life by a wide margin.

Mature lifecycle — what that means for a BOM freeze

Frequently asked questions

What does 4-axis PTP control mean for my application?

Point-to-point (PTP) control means each of the four axes moves independently between programmed positions with its own acceleration/deceleration profile. The module handles the trajectory math so the PLC CPU is free to manage logic and HMI communication. Typical applications include pick-and-place, indexing conveyors, and multi-station assembly machines.

Will the QD75P4 work in a panel wired for an FX5-8EX/ES?

No — the QD75P4 is a Q-series positioning module that mounts on a Q-series backplane, while the FX5-8EX/ES is an iQ-F series digital input module with a different form factor, bus interface, and wiring scheme. They are not mechanically or electrically interchangeable.
