Bonfiglioli Vectron EM-IO-03 Expansion Module Dual Analog Output and PTC Configuration

Node ID=1~63: Slave address

5.3 NMT State Machine and Startup

CANopen standard tri state management:

Pre Operational: SDO communication only

Operational: Both SDO and PDO are allowed

Stopped: All communication is prohibited

The master station switches the slave station to Operational through the NMT command "Start Remote Node" (command code=1). Parameter 904 (Boot Up Delay, 3500~50000ms) sets the interval for sending periodic startup commands.

5.4 Virtual Links

EM-IO-03 supports horizontal data transmission between frequency converters through TxPDO/RXPDO. Each TxPDO supports Boolean, Word, and Long data type mapping:

TxPDO channel Boolean parameter Word parameter Long parameter

TxPDO1 946~949 950~953 954~955

TxPDO2 956~959 960~963 964~965

TxPDO3 966~969 972~975 976~977

Common source number:

Boolean source: 740=control word, 161=running status, 163=target value reached

Word source: 9063=percentage reference value 1133=output percentage

Long source: 900=output frequency, 62=reference frequency value

Simulation input characteristic curve configuration

The analog input of EM-IO-03 supports two-point linear characteristic curve mapping (parameters 564~567), which is suitable for linearization of nonlinear sensor signals.

Operation mode (parameter 562):

Typical Applications of Mode Functions

1. Bipolar complete mapping according to characteristic points ± 10V bidirectional control

11- Unipolar negative X-axis value mapping to 0 unidirectional speed control

21- Unipolar 2~10V/4~20mA input range limited to 20%~100% active zero position signal

101- Bipolar absolute value negative Y-axis value mapping to positive absolute value control

Tolerance band (parameter 560): 0%~25%, factory 2%, used to expand the zero crossing range and avoid direction switching oscillation.

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

Load assessment: A total load rate of ≤ 80% for all TxPDOs is normal, 80%~90% is critical, and>90% is unacceptable.
