4 Parameter description
format
In the following sections descriptions are given for the advanced
parameter set. With each parameter the following information block is
given.
The top row gives the menu.parameter number and the parameter
name. The other rows give the following information.
Drive modes
The drive modes are the modes in which this parameter is accessible. If
the parameter is not present the parameter is skipped when accessing
from the keypad. The following types are possible.
Open-loop - with the Unidrive SP hardware and open loop drive mode
selected. The control strategy is V/F mode with fixed boost or open-loop
vector.
Closed-loop vector - with the Unidrive hardware and closed-loop vector
mode selected. The control strategy is rotor flux oriented vector control
with closed-loop current operation for induction motors. The drive can be
operated with or without position feedback.
Servo - with the Unidrive hardware and servo mode selected. The
control strategy is rotor flux oriented vector control with closed-loop
current operation for permanent magnet synchronous motors. The drive
must be operated with position feedback.
Regen - with the Unidrive hardware and regen mode selected. The drive
operates as a PWM rectifier.
Coding
The coding defines the attributes of the parameter as follows:
This guide will show all bit parameters (with the Bit coding), as having a
parameter range of "0 to 1", and a default value of either "0" or "1". This
reflects the value seen through serial communications. The bit
parameters will be displayed on the SM-Keypad (if used) as being "OFF"
or "On" ("OFF"= 0, "On" = 1).

SP Spare: not used
FI
Filtered: some parameters which can have rapidly changing
values are filtered when displayed on the drive keypad for
easy viewing.
DE
Destination: indicates that this parameter can be a
destination parameter.
TE Text: the parameter uses text strings instead of numbers.
VM Variable maximum: the maximum of this parameter can vary.
DP
Decimal place: indicates the number of decimal places used
by this parameter.
ND
No default: when defaults are loaded (except when the drive
is manufactured or on EEPROM failure) this parameter is not
modified.
RA
Rating dependant: this parameter is likely to have different
values and ranges with drives of different voltage and current
ratings. This parameters is not transferred by SMARTCARDs
when the rating of the destination drive is different from the
source drive.
NC
Not cloned: not transferred to or from SMARTCARDs during
cloning.
NV Not visible: not visible on the keypad.
PT Protected: cannot be used as a destination.
US
User save: saved in drive EEPROM when the user initiates a
parameter save.
RW Read/write: can be written by the user.
BU
Bit default one/unsigned: Bit parameters with this flag set to
one have a default of one (all other bit parameters have a
default of zero. Non-bit parameters are unipolar if this flag is
one.
PS
Power-down save: automatically saved in drive EEPROM at
power-down.
