Short and extended menus
When the LVD drive is in default status, only a limited number of parameters are
displayed. These parameters are the only ones required for applications in which the LVD is
employed as a straightforward frequency converter, i.e. you are not using the advanced
functions of the drive (e.g. using LVD with a Numerical Control or an intelligent axis control
card). Switch between short and extended menus using b99.6: short menu with status 0,
extended menu with status 1.
Short menu parameters are:
Pr0 Real speed of motor shaft in rpm.
Pr1 Main analog reference offset.
Pr2 Analog reference full scale: speed value in rpm corresponding to 10V reference signal.
Pr8 Acceleration/deceleration ramp values in seconds per 1000 rpm with millisecond
resolution. If the acceleration and deceleration ramps required different settings, use
parameters Pr9, Pr10 and Pr11, which are available only in the extended menu.
Pr16 Integral gain of speed control loop.
Pr17 Speed control loop damping.
Pr19 Peak current delivered to drive expressed as a percentage of the peak rated value of the
drive.
Pr29 Number of motor poles.
Pr32 Rated speed (rpm).
Pr33 Rated current that can be delivered by the drive (can be maintained indefinitely)
expressed as a percentage of the rated peak current of the drive.
Pr35 Instantaneous current requested by the motor expressed as a percentage of drive rated
peak current.
Pb99 Bit parameter for basic commands.
In addition to the previous parameters, the extended menu provides access to all the other
parameters and the pico-PLC instructions.
Restoring default parameter values
If you wish to set up the drive using the manufacturer's factory default values, proceed as
follows:
- disable the drive via hardware (connector X7 pin 1 open)
- power up the drive
- the display will show the message “IdLE”
- set b99.7 and b99.13 to zero
- enter command b99.12
- save the settings with b99.14 and b99.15.
