Installation of Bonfiglioli Vectron EM-IO-02 Expansion Module and PTC Temperature Monitoring Configuration

101- Bipolar absolute value: negative Y-axis value mapped to positive reference value

Tolerance band (parameter 560): used to expand the zero crossing range of the reference value, avoiding frequent switching of rotation direction near zero, with a range of 0.00%~25.00% and a factory value of 2.00%.

5.2 Digital input as speed sensor

The three-way digital input can be configured as an incremental speed sensor interface through parameter 493:

Mode 4- Quadruple Frequency Evaluation: Dual channel speed sensor with 4 edge evaluations per turn

Mode 104- Four fold Reverse: Speed value is reversed

Mode 1004/1104- with reference pulse: adding reference pulse for sensor monitoring

Index mark (parameter 494): range 1~8192, factory value 1024. The maximum division mark is determined by the maximum frequency limit of the digital input (150kHz).

Actual speed source selection (parameter 766): 1=speed sensor 1 (body), 2=speed sensor 2 (EM-IO-02).

5.3 Fixed frequency extension

EM-IO-02 expands the fixed frequency to 8 groups through parameter 131 (Fixed frequency change over 3):

Fixed frequency parameter FF3=0 FF3=1

Fixed frequency 5 485 0 1

Fixed frequency 6 486 1 1

Fixed frequency 7 487 1 0

Fixed frequency 8 488 0 1

Bus load planning reference

System bus capacity planning is crucial for reliable communication. PDO message transmission time at different baud rates:

Baud rate (kBaud) message transmission time (μ s)

1000 140

500 280

250 560

125 1120

100 1400

50 2800

Bus load assessment criteria:

≤ 80%: Normal

80%~90%: critical

90%: unacceptable
