The drive is preset with default values designed to meet the requirements of the majority of
applications. With the default values the pico-PLC in the drive runs the program described in
appendix G, so the following functions will be present on the input and output terminal
boards:
The functions on terminals 12, 13 and 14 must be enabled by setting bit b90.10 to one.
This requires access to the extended parameters menu.
The default PLC program controls parameter Pr5 in addition to timer 1 (Pr92) and bits
b40.0, b40.4, b40.5, b40.6, b40.12 so in this case the above binary parameters and switches
cannot be utilised unless the pico-PLC is disabled (b99.13=0) or the basic program is
modified.
Short and extended menu
When the HPD 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 HPD is
employed as a straightforward frequency converter, i.e. you are not using the advanced
functions of the drive (e.g. using HPD with a Numerical Control or an intelligent axis control
card). Switch between short and extended menu using b99.6.
Short memory parameters are:
Pr0 Real speed of motor shaft in rpm.
Pr1 Analogue reference offset (terminals 1 and 2 of terminal board X2 ).
Pr2 Analogue reference full scale: speed value in rpm corresponding to 10 V reference
signal.
Pr8 Acceleration/deceleration ramp values in seconds per 1000 rpm
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).
