Name [ID] Description Def.
■ Ignor. zero sig.
IRC1
Ignore zero (index) signals from IRC1.
□ Enable gear
ratio tuning
Enables fine tuning of the gear ratio. Enabling this option can have a negative effect on the
accuracy of the calculation, as calculations may be performed in the floating point
arithmetics.
7.6.6 IRC2/ARC
Group of parameters number [826]
Setting the IRC2 or ARC position and speed measurement parameters.
MENU \ SETTINGS \ INPUTS AND OUTPUTS \ IRC2/ARC
Name [ID] Description Def.
IRC2/ARC type [824] Type of connected module for measurement of second position/speed. IRC2
IRC2 No absolute position sensor module connected.
ARC Absolute position sensor module connected.
RM-SERVO
RM-SERVO module for reading the absolute position over serial communication is
connected.
IRC2 pulses [827] Number of IRC pulses per turn from the sensor nameplate. 1024
0 ÷ 40000
For low-speed motors sensor with higher pulses per turn are recommended. For high
speed motors sensors with lower pulses per revolution are recommended.
Speed calc. period
IRC2 [828]
Speed calculation period of IRC2. Increasing the parameter values
increases the speed resolution and decreases the quantization noise,
however, a high value can cause a negative effect on the speed control
quality.
2
1 ÷ 100
IRC2/ARC direction
[829] Polarity of the IRC2 / ARC speed evaluation. The equivalent of direct (A-
B), inverted (B-A) for IRC2.
Direct
Direct Polarity of position and speed is determined by cabling of the sensor.
Inverted
By selecting this option, polarity of position and speed can be inverted without the
need for re-cabling the sensor.
Num. IRC2/ARC
ratio [1533]
Numerator of gear ratio of IRC2/ARC. 1
1 ÷ 32767
Den. IRC2/ARC ratio
[1625]
Denominator of gear ratio of IRC2/ARC. 1
1 ÷ 65535
ARC delay
compensation
[1537]
Compensation of time delay between the receiving new information from
RM-SERVO and its processing.
0,0 µs
0,0 µs ÷ 300,0 µs
Tune of IRC2/ARC
gear ratio [1626]
Fine tune of IRC2/ARC gear ratio. 1,0000
0,0100 ÷ 100,0000
IRC2/ARC spec.
settings [1619]
Special settings of IRC2 or ARC encoders.
Ignor. zero
sig. IRC2
■ Ignor. zero sig.
IRC2
Ignore zero (ndex) signals from IRC2.
□ Enable gear ratio
tuning
Enables fine tuning of the gear ratio. Enabling this option can have a negative effect
on the accuracy of the calculation, as calculations may be performed in the floating
point arithmetics.
7.7 FUNCTIONS
Group of parameters number [532]
Setting an selection of different optional functions of the UNIFREM frequency converter.
