Kollmorgen PCMM
First-generation EtherCAT multi-axis master controller supporting all five IEC 61131-3 languages plus PLCopen motion, now closed to new applications.
Kollmorgen lists this series as legacy. The manufacturer's recommended replacement: kollmorgen-pcmm2g. We can help with spares for installed machines, a migration to the replacement, or an alternative. Find a replacement.

Notes on this data
Page states PCMM is not available for new applications and points to PCMM2G. '20 axes or more' at 1 kHz for low-complexity machines; about 8 axes at 4 kHz.

Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Kollmorgen part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 2 series from our supply network are the closest match on published figures.
Slim 54 mm EtherCAT motion controller programmed in CODESYS, running up to 32 synchronised axes on a 1 ms cycle with RP20 I/O expansion.
| Published maximum | PCMM | AK (AK8 / AK840) |
|---|---|---|
| Axes | 20 | 32 meets or exceeds |
CODESYS-based PLC/motion controller with EtherCAT for 8, 16 or 32 axes plus 6 local pulse axes, dual-core SOC+FPGA and 32-module R2 I/O expansion.
| Published maximum | PCMM | MC500 (MC508CS / MC516CS / MC532CS) |
|---|---|---|
| Axes | 20 | 32 meets or exceeds |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
