b42.6 Torque compensation . Default=1. When set to 1 torque compensation is
implemented to improve linearity of response.
b42.7 Reserved.
b99.6 Extended menu enable . Default=0. Set to 1 to enable the extended menu.
b99.7 Security . Default=0. Set to 1 to prevent parameter modification.
B99 . 8 Automatic reset undervoltage. Default =0. if used the backup function, the
parameter must be 1, and in this case the undervoltage alarm is automatically reset.
b99.13 pico-PLC status. Default=1. If on 1 the PLC program is run, if on zero the program
is not run and the PLC instructions can be modified if required.
4.4. Basic commands
To transmit the following commands b99.7 must be on zero. For commands b42.3 and
b94.1, b99.6 must be on one.
b42.3
Re-initialise serial line. Command to reinitialise the serial line when the
communication speed (Pr26) has been modified. In any event, the serial line is
initialised when the drive is started up.
b94.1 Reset main reference offset. This command automatically sets parameter Pr1 in
order to reset any voltage offset on the main analogue reference. This procedure is
only possible if the absolute offset value is less than 200 mV.
b99.9 Current offset calibration request . The command is accepted only if the drive is
disabled. The calibration procedure is executed when the drive is started up.
b99.10 Alarm reset . This command resets Pr23 and Pr24; if the alarm persists it is shown
on the display. The 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.
If the backup power supply is present (terminals 8 and 9 on X3), when mains power
is restored to the terminals on X4 you must wait 10 seconds before transmitting the
undervoltage alarm reset command and enabling the drive.
b99.11 Operating mode parameter default values. This command sets current operating
parameters to default values. The command is executed only if b40.2 = 0.
b99.12 Default values. This command sets all parameters to default values and cancels the
values used by the operating modes; it also sets the pico-PLC program as described
in appendix G. If a checksum alarm is present, Pr23 and Pr24 are set to zero so that
the alarm can be reset. The command is executed only if b99.13 = 0.
b99.14 Save pico-PLC instructions. Saves the pico-PLC program. If an error occurs while
saving, “retry” is shown on display: in this case transmit the command again.
b99.15 Save parameters. Stores all parameters. This command is not possible in the
presence of a checksum error; in this case, set default parameters, reset the alarm and
then save the new parameterisation settings. If an error occurs while saving, “retry”
is shown on display: in this case transmit the command again.
