Program features 155 Motor temperature measurement through the standard I/O This section describes the temperature measurement of one motor when the drive I/O terminals are used as the connection interface. Motor temperature can be measured using PT100 or PTC sensors connected to analog input and output. One sensor Motor Three sensors AI1 AI1 Motor GND T T T GND T AO AO GND 3.3 nF GND 3. Program features It is also possible to monitor motor temperature by connecting a PTC sensor and a thermistor relay between the +24 V DC voltage supply offered by the drive and a digital input. The figure below displays the connection. Par. 3501 = THERM(0) or THERM(1) Thermistor relay DI1…5 +24 V DC T Motor WARNING! According to IEC 664, the connection of the motor thermistor to the digital input requires double or reinforced insulation between motor live parts and the thermistor. Program features 157 Control of a mechanical brake The mechanical brake is used for holding the motor and driven machinery at zero speed when the drive is stopped, or not powered. Example The figure below shows a brake control application example. WARNING! Make sure that the machinery into which the drive with brake control function is integrated fulfills the personnel safety regulations.

Program features 161 Jogging The jogging function is typically used to control a cyclical movement of a machine section. One push button controls the drive through the whole cycle: When it is on, the drive starts, accelerates to a preset speed at a preset rate. When it is off, the drive decelerates to zero speed at a preset rate. The figure and table below describe the operation of the drive. Program features Note: The jogging speed overrides the constant speeds. Note: The jogging uses ramp stop even if parameter 2102 STOP FUNCTION selection is COAST. Note: The ramp shape time is set to zero during the jogging (ie linear ramp). Jogging function uses constant speed 7 as jogging speed and acceleration/deceleration ramp pair 2. It is also possible to activate jogging function 1 or 2 through fieldbus. Jogging function 1 uses constant speed 7 and jogging function 2 uses constant speed 6. Program features 163 Timed functions A variety of drive functions can be time controlled, eg start/stop and EXT1/EXT2 control. The drive offers • four start and stop times (START TIME 1…START TIME 4, STOP TIME 1…STOP TIME 4) • four start and stop days (START DAY 1…START DAY 4, STOP DAY 1…STOP DAY 4) • four timed functions for collecting the selected time periods 1…4 together (TIMED FUNC 1 SRC…TIMED FUNC 4 SRC) • booster time (an additional booster time connected to timed functions).

Fieldbus control with embedded fieldbus 307 Fieldbus control interface The communication between a fieldbus system and the drive consists of 16-bit input and output data words (with the ABB drives profile) and 32-bit input and output words (with the DCU profile). Control word and Status word The Control word (CW) is the principal means of controlling the drive from a fieldbus system. The Control word is sent by the fieldbus controller to the drive. Fieldbus control with embedded fieldbus Fieldbus references Reference selection and correction Fieldbus reference (called COMM in signal selection contexts) is selected by setting a reference selection parameter – 1103 REF1 SELECT or 1106 REF2 SELECT – to COMM, COMM+AI1 or COMM*AI1.

The following diagrams illustrate how group 10 parameters and the sign of the fieldbus reference interact to produce the reference REF1/REF2. Direction determined by the sign of COMM Par.

The register addresses that do not correspond with drive parameters are invalid. If there is an attempt to read or write invalid addresses, the Modbus interface returns an exception code to the controller. See Exception codes on page 314. The following table gives information on the contents of the Modbus addresses 40001…40012 and 40031…40034.

Fieldbus control with embedded fieldbus 315 Communication profiles The embedded fieldbus supports three communication profiles: • DCU communication profile (DCU PROFILE) • ABB drives limited communication profile (ABB DRV LIM) • ABB drives full communication profile (ABB DRV FULL). The DCU profile extends the control and status interface to 32 bits, and it is the internal interface between the main drive application and the embedded fieldbus environment.
