c) Based on the limits to the number of I/O references above, the maximum number of
Two-axis Motion Modules that can be used depends on the CPU Module, as shown
below.
Maximum Number of Two-axis Motion Modules that Can Be Used

Remarks
CPU20
CPU21
1,024 512 8 D All input relays and
output coils will be used
for the MC15 Modules.
D There will be 64 unused
I/O registers
CPU30
CPU35
4,096 512 16 D There will be 2,944
unused input relays and
output coils.
D There will be 8 unused
I/O registers.
Note (1) When using Remote Stations, the limit is 8 Modules for the CPU20 and CPU21 and 12
Modules for the CPU30 and CPU35
(2) When using a PS10 or PS11 Power Supply Module, a single Two-axis Motion Module
uses 750 mA of the 7 A current available, so a maximum of 9 Modules can be used per
Rack.
2) Installation Locations
a) The Two-axis Motion Module requires one slot and can be mounted as shown below.
(1) If not using the absolute position detecting function, the Module can be mounted
to any slot on any Rack.
(2) If using the absolute position detecting function, the Module can be mounted to
any slot on the Mounting Base of the CPU Rack.
