Parameter update times
The SM-I/O Plus Solutions Module is a dumb Solutions Module and is controlled directly by the drive's main processor. The update time for some
functions are affected by the number of dumb Solutions Modules installed to the drive. The update time for these functions is the sum of the update
times for all dumb Solutions Modules installed to the drive, called the combined update time. This module contributes 8ms to the combined update
time. The update time for dumb Solutions Modules can vary, for example, the update time for SM-Encoder plus and SM-resolver modules is 4ms.
Therefore if an SM-Encoder plus and an SM-I/O plus module are installed to a drive, then the combined update time is 12ms. In this example all
parameters shown as having an update rate of "combined update time" would be updated every 12ms.
When a digital input or an analog input is the source for a parameter outside the Solutions Module menu the data from the input is written to the
destination parameter at the combined update time rate. When a digital output or the analog output is the destination for a parameter outside the
Solutions Module menu, the data is taken from the source parameter at the rate defined by the combined update time.
The menu for the relevant slot appears for the new Solutions Module category with the default parameter values for the new category. When no
Solutions Module is installed in the relevant slot this parameter is zero. When a Solutions Module is installed this parameter displays the identification
code.
201: SM-I/O Plus
The new parameters values are not stored in EEPROM until the user performs a parameter save. When parameters are saved by the user in the drive
EEPROM the option code of the currently installed Solutions Module is saved in EEPROM. If the drive is subsequently powered-up with a different
Solutions Module installed, or no Solutions Module installed where one was previously installed, the drive gives a SLx.dF or SLx.nf trip.
