SM-I/O Lite & SM-I/O Timer

The Commander SK SM-I/O Lite & SM-I/O Timer options have an analog input that operates with a 11 bit resolution in both voltage and current

modes.

The analog output has a resolution of approximately 13 bits (± 1.25mV resolution in voltage mode and ± 2.5μA resolution in current mode).

Input / outputs - sample times / update rates

The communications between the drive and the Solutions Module is through a synchronous serial link operating at 100kHz. The update rate of the

I/O is dependant on the number of I/O being used.

If fast update rates of I/O are required, the drive I/O should be used or the Solutions Module I/O loading should be kept to a minimum.

Sample calculation of update rate:

Analog input (2) + analog output (3)+ digital input (2) + relay output (2) + background (5) = 14 ms

* When the analog input is routed to precision reference parameters, Pr 1.18 and Pr 1.19, the worst-case update time is 4 x 2 = 8 ms

If a 32 bit parameter is used as a source parameter on a Solutions Module, then it should be routed via a Menu 18 parameter e.g. Pr 18.12.

The encoder reference input is only active when the destination parameter (Pr 15.59) is routed to a valid parameter.

The new parameter values are stored automatically by the drive. If the drive is subsequently powered up with a different Solutions Module installed or

no Solutions Module installed when one was previously installed. The drive will trip on SL.dF or SL.nF.

This parameter shows the version of software programmed into the Solutions Module. The software sub version is displayed in Pr 15.51.

These two parameters display the software version in the form of:

Pr 15.02 = xx.yy

Pr 15.51 = zz

If the SM-I/O Lite/ SM-I/O Timer analog input is programmed in any of the modes 2 to 5 (see Pr 15.38) then this bit is set if the current input falls below

3mA. This bit can be designated to a digital output to indicate that the current input is less than 3mA.
