CONFIGURE DRIVE
This block contains many of the parameters
required for configuring the drive.
CONFIGURE ENABLE: The operation of the
Block Diagram is suspended and all Operator
Station LEDs will flash whilst CONFIGURE
ENABLE = TRUE.
Note:
The CONFIGURE ENABLE
parameter is also available in the
following MMI menus for ease of

NOM MOTOR VOLTS
521
100 to 875 VOLTS
Sets the 100% value for Armature Volts VA. Set this value to match the motor in use.
(Refer to ARMATURE V CAL in the CALIBRATION function block).
ARMATURE CURRENT
523
drive dependent AMPS
Sets the 100% value for Armature Current IA. Set this value to match the motor in use.
FIELD CURRENT
524
drive dependent AMPS
Sets the 100% value for Field Current IF. Set this value to match the motor in use. Note:
this should be set to a minimum value if in Field Voltage control - see FLD. CTRL MODE.
FLD. CTRL MODE
209
See below
(FLD.CTRL MODE)
There are two field control modes:
(a)
Field Voltage Control is an open loop phase angle control to give a
certain voltage output.
(b)
Field Current Control is a closed loop current control for accurate field
control or expansion to field weakening.

CURRENT CONTROL
FIELD VOLTAGE RATIO
210
0.00 to 100.00 % (h)
(FLD. VOLTS RATIO)
This parameter controls the output voltage from the open loop voltage control. The ratio is
defined as the DC output voltage over the AC RMS input voltage.
The default setting is equivalent to a single-phase diode rectifier.
SPEED FBK SEL
47
See below
(SPEED FBK SELECT)
Determines the source of the speed feedback signal. The default, ARM VOLTS FBK, uses
internal circuitry to derive the speed feedback. The other selections require the appropriate
external device to provide the feedback signal.
0 : ARM VOLTS FBK
1 : ANALOG TACH
2 : ENCODER
3 : ENCODER/ANALOG - for SSD Drives use
ENCODER RPM
22
0 to 6000 RPM
Motor top speed setting (100%) when using encoder feedback.
ENCODER LINES
24
10 to 5000
The 5901 Microtach has 1000 lines per revolution as standard. Proprietary encoders of
other specifications can be normalised by setting this parameter as appropriate.
ENCODER SIGN
49
NEGATIVE / POSITIVE
Since the encoder feedback cannot be reversed electrically, the signal polarity can be
reversed by the control software.
