3.4 Basic commands
To transmit the following commands b99.7 must be set to 0. In addition, for commands
b42.3 and b94.1, b99.6 must be set to 1.
b42.3
Serial line re-initialisation.
This commands serves to re-initialise serial line
communications if the serial line transmission rate (Pr26) has been altered. The serial
line is initialised whenever the drive is powered up.
b94.1
Main reference offset zero setting command.
This command is used to set
parameter Pr1 automatically in such a way as to reset possible voltage offset values
on the main analog reference. This procedure is only permitted if the absolute value
of the offset is less than 200 mV.
b94.8
Quote compare
(see heading
Other useful functions
).
b94.9
Quote compare
(see heading
Other useful functions

b94.10 Quote compare
(see heading
Other useful functions
).
b94.11 Quote compare
(see heading
Other useful functions
).
b94.12 Homing function 1
(see heading
Other useful functions
).
b94.13 Homing function 2
(see heading
Other useful functions
).
b99.10 Alarm reset
. This command resets Pr23 and Pr24; if the alarm persists it will appear
on the display. This command is not accepted in the presence of checksum errors
(Pr23=10, 11); in this case set default parameters (b99.12) and then reset the alarm.
b99.11
Operating mode parameters default values.
This command sets the current
operating mode parameters to the default values. It is executed only if b40.2 = 0.
b99.12
Default values.
Sets all parameters to their default values, zero setting those utilised
by the operating modes; also, it applies the pico-PLC program as described in
appendix
F
. If checksum alarms are present (Pr23 and Pr24), these will be reset,
thereby allowing subsequent alarm reset. The command is executed only if b99.13=0.
b99.14
Store pico-PLC instructions.
Saves the pico-PLC program. This command is not
accepted if a checksum error alarm is active; in this case set default parameters, reset
the alarm and then save the new parameterisation.
b99.15
Store parameters.
Stores all parameter settings. This command is not accepted if a
checksum error alarm is active; in this case set default parameters, reset the alarm
and then save the new parameterisation.
