27. July 98 SECTION 3 COMMANDS AND PROTECTIONS 3 1 General Features For serial communication according to standard RS485 DBM drives are connected in parallel multidrop and in slave configuration whereas the CNC the PC or the keyboard are in master configuration This is because the protocol is configured so that the drives are able to communicate only if inquired by the master to avoid contentions on the line As a consequence all the commands have been configured individually single axis questioned except those for which an answer is not foreseen therefore all the drives can be reached simultaneously There are 3 kinds of command e status monitoring Monitor commands on the status of the drive which displays axis configuration and eventual faults e data monitoring Monitor commands for displaying memorized motion parameters e g limit 100 etc e data command input Execute commands for setting and changing parameters e g speed pole number acceleration deceleration etc Remark if a mistake has been made while digitizing it is possible to reset the command by pressing CH CARRIAGE RETURN The commands are in ASCII format 1 bit start 8 bit data 1 bit parity even 1 bit stop Serial communication speed can vary from 1200 to 19200 Baud 58 6 July 98 Command syntax is as follows status monitoring B address COMMAND data monitoring B address COMMAND data input B address COM

Since the implementation of the scheme in Fig 2 is analog proportional and integral gains of the current controller are determined by the value of resistors and capacitors used For the purpose of allowing the matching of DBM with a non standard motor these components are mounted on a removable plug in modules namely the PWM90 hybrids These hybrids are fitted into the drive during the factory test At this time the current gain is adjusted according to the motor that is going to be used in conjunction with the drive Current gains are optimized in the sense of maximizing the current loop bandwidth while still keeping the noise current ripple and overshoot at an acceptable level The bandwidth of the current loop lies in the range of 900 1200 Hz In terms of the torque response time the motor fed from a DBM will respond to the torque command with a rise time 200 us 118 6 July 98 5 4 Speed and Position Sensing The DBM multi axis drive is equipped with an interface for resolver type shaft sensors These sensors are preferred for the reason of inherent absolute position sensing much wider operating temperature range than the optical devices and a robustness intrinsic to the resolver mechanical mounting that is the one of an electric machine Resolvers have a pair of detection windings on the stator side name SINE and COSINE winding spatially displaced by 90 degrees Excitation of the resolver is performed by a 10kHz 7Vrms si
