3.1.2Interconnecting signals (BICO technology)

A state-of-the-art drive unit must be able to interconnect internal and external signals (setpoint / actual values and control / status signal). This interconnection functionality must have a high degree of flexibility in order to be able to adapt the drive to new applications. Further, a high degree of usability is required, which also fulfills standard applications. This is the reason that within the MICROMASTER series of drive units, BICO technology (→ flexibility) and fast parameterization using parameters P0700 / P1000 (→ usability) or P0719 (→ combination P0700/P1000) have been introduced to be able to fulfill both of these requirements.

3.1.2.1Selecting the command source P0700 / selecting the setpoint source P1000

The following parameters can be used to quickly interconnect setpoints and control signals:

P0700 "Selection of command source"

P1000 "Selection of setpoint source"

These parameters are used to define via which interface the drive inverter receives the setpoint or the power-on/power-off command. The interfaces, listed in Table 3-2 can be selected for the command source P0700.

Table 3-2	Parameter P0700
Parameter values		Significance / command source
0		Factory default
1		BOP (operator panel, refer to Section 3.2.1)
2		Terminal strip
4		USS on BOP link
5		USS on COM link
6		CB on COM link

The following internal or external sources / interfaces can be selected for the frequency setpoint source P1000. In addition to the main setpoint (1st position), a supplementary setpoint (2nd position) can be selected (refer to Table 3-3).
