SM-Encoder Pl structure display
x.39 Freeze flag
RW Bit
OFF (0) or On (1)
Update rate: 4ms x number of dumb modules
This Solutions Module does not have its own freeze input, therefore the freeze input must come from a SM-Applications or SM-Universal Encoder
Plus. The freeze data is processed every 4ms x number of dumb modules installed. If a freeze has occurred and the freeze flag (Pr x.39) is zero, the
position data is stored in Pr x.35 and Pr x.36 and the freeze flag is set. The freeze flag must be reset by the user before the next freeze event is
stored.
x.45 Position feedback initialised
RO Bit
OFF (0) or On (1)
Update rate: 4ms x number of dumb modules
At power-up Pr x.45 is initially OFF (0), but is set to On (1) when the SM-Encoder Plus can provide position feedback. Pr x.45 then remains at On (1)
while the drive is powered-up.
x.49 Lock position feedback
RW Bit
OFF (0) or On (1)
Update rate: Background write
If Pr x.49 is set to one, Pr x.04 and Pr x.05 are not updated. If this parameter is zero, Pr x.04 and Pr x.05 are updated normally.
x.50 Solutions Module error status
RO Uni
0 to 255
The error status is provided so that the only one option error trip is required for each Solutions Module slot. If an error occurs, the reason for the error
is written to this parameter and the drive may produce a 'SLX.er' trip, where X is the slot number. A value of zero indicates the Solutions Module has
not detected an error, a non-zero value indicates that an error has been detected. (See Table 5-15 on page 280 for the meaning of the values in this
parameter). When the drive is reset, this parameter is cleared.
The Solutions Module includes a temperature monitoring circuit. If the PCB temperature exceeds 90°C, the drive fan is forced to operate at full speed
(for a minimum of 10s). If the temperature falls below 90°C, the fan can operate normally again. If the PCB temperature exceeds 100°C, the drive is
tripped and the error status is set to 74.
