b90.X Digital input X status. If X is greater than 7, parameter with save facility at user’s
disposal (b90.0 = drive enable).
b91.Y Digital input Y status. If Y is greater than 7, parameter with save facility at user’s
disposal. Parameter Pb91 is not saved at power up and is definitely at zero.
Pr92 First PLC timer. Every 6.144 ms if Pr92 is not at 0 the timer is decreased, if set to
zero b99.0 is set at 1.
Pr93 Second PLC timer. Every 6.144 ms if Pr93 is not at 0 the timer is decreased, if set
to zero b99.1 is set to 1.
b94.0 Forces a double word formatted operation. When the drive is powered up this
parameter is on zero. If it is on one, the first mathematical operation of the pico-PLC
is executed setting the three operands as double word type; after the operation is
executed b94.0 is automatically set to zero.
If Pr60..Pr68 are utilised, double word formatting is automatic (see text).
b94.5 Disables the first fast input (b94.5=0). Set to zero at power-up.
b94.6 Disables the second fast input (b94.6=0). Set to zero at power-up.
b94.7 Disables the third fast input (b94.7=0). Set to zero at power-up.
b99.0 First timer status. At 1 if Pr92 = 0
b99.1 Second timer status. At 1 if Pr93 = 0
b99.2 At 1 if the result of the last PLC operation is negative.
b99.3 At 1 if the result of the last PLC operation is zero.
b99.13 PLC status. Default=1. If set to 1 the PLC program is executed, if on zero the
program is not executed and modification of PLC instructions is enabled.
