EM-RES-03 6510/07
6.4.2 Actual speed source
Switch-over is effected via Actual Speed Source
766. If the resolver delivers the actual
value si
gnal for the speed controller, speed sensor 2 must be selected as the source In
the basic setting, speed sensor 1 is used as the actual value source.
Operation mode Function
1 - Speed sensor 1
The actual speed source is speed sensor 1 of the
basic device (factory setting).
2 - Speed sensor 2
The actual speed source is speed sensor 2 of the EM-
RES-03 expansion module.
6.4.3 Evaluation mode
If a synchronous motor which is not from BONFIGLIOLI should be connected to the
resolver input it can be necessary to chan
e the si
n of the sinus track. This can be set
via parameter
Evaluation Mode 492.
Evaluation Mode 492
Function
0 - Bonfiglioli Factory setting. For Bonfiglioli synchronous motors.
1 - inverted The sign of the sinus track is changed.
6.5 Frequency and percentage reference channel
The varied functions for the specification of the reference values are connected in the
various configurations by the frequency or percentage reference channel. The
Refer-
ence frequency source
475, and the Reference percentage source 476 determine the
additive connection of the available reference sources as a function of the installed
hardware.
Operation mode Function
2 - EM-S1INA, absolute value Reference source is the analog input EM-S1INA
4 -
MFI1A + EM-S1INA, abso-
lute value
Reference sources are the multifunctional input
MFI1A and the analog input EM-S1INA
14 -
MFI1A + EM-S1INA + FF,
absolute value
Reference sources are the multifunctional input
MFI1A, analog input EM-S1INA and fixed frequency
FF
24 -
MFI1A + EM-S1INA + MP,
absolute value
Reference sources are the multifunctional input
MFI1A, analog input EM-S1INA and the motor po-
tentiometer function MP
102 to 124 Operation modes with signs (+/-)
Additional to the operation modes listed, those stated in the operating instructions of
the frequency inverter in the chapter "Frequency reference channel“, and in the chap-
ter "Percentage reference channel“ also apply.
6.6 Actual value display
The actual value of speed sensor 2 can be read via the parameters Frequency
pee
sensor 2 219 and Speed, speed sensor 2 220.
The analog input signal on analog input EM-S1INA is displayed via the actual value
parameter
Analog input EM-S1INA 253.
