Fieldbus Adapter PID Control Setpoint Source Using the fieldbus for the PID control setpoint requires: • Drive parameter values set as defined below. • Fieldbus controller supplied setpoint value in the appropriate location. (As defined in Analog output control above.
Fieldbus Adapter Diagnostics – FBA Fault Handling Serial Communication Diagnostics The MD5 provides fault information as follows: Besides the drive fault codes, the FBA module has diagnostic tools. Refer to the user’s manual supplied with the FBA module. • The control panel display shows a fault code and text. See page 74 for a complete description. • Parameters 0401 LAST FAULT, 0402 PREVIOUS FAULT1 and 0403 PREVIOUS FAULT2 store the most recent faults.
Fieldbus Adapter Generic Profile Technical Data Overview Reference The generic profile aims to fulfill the industry-standard drive profile for each protocol (e.g. PROFIdrive for PROFIBUS, AC/DC Drive for DeviceNet). As described earlier in Control interface, the REFERENCE word is a speed or frequency reference. Control Word Reference Scaling As described earlier in Control interface the CONTROL WORD is the principal means for controlling the drive from a fieldbus system.
Diagnostics Diagnostics WARNING Do not attempt any measurement, parts replacement or other service procedure not described in this manual. Such action will void the warranty, may endanger correct operation, and increase downtime and expense. DANGER All electrical installation and maintenance work described in this chapter should only be undertaken by qualified service personnel. The Safety instructions on the first pages of this manual must be followed.
Diagnostics Diagnostics Correcting Faults The recommended corrective action for faults is: • Use the Fault listing table below to find and address the root cause of the problem. • Reset the drive. See Fault Resetting on page 78. Table 53: Fault Listing Fault Code Fault Name In Panel Description and Recommended Corrective Action 1 OVERCURRENT Output current is excessive. Check for and correct: • Excessive motor load. • Insufficient acceleration time (parameters 2202 ACCELER TIME 1).
Diagnostics Table 53 continued: Fault Listing Fault Code Description and Recommended Corrective Action Possible ground fault detected in the motor or motor cables. The drive monitors for ground faults while the drive is running and while the drive is not running. Detection is more sensitive when the drive is not running and can produce false positives. Possible corrections: • Check for/correct faults in the input wiring. • Verify that motor cable does not exceed maximum specified length.

Diagnostics Fault Resetting History The MD5 can be configured to automatically reset certain faults. Refer to parameter Group 31: Automatic Reset on page 33. For reference, the last three fault codes are stored into parameters 0401, 0412, 0413. For the most recent fault (identified by parameter 0401), the drive stores additional data (in parameters 0402…0411) to aid in troubleshooting a problem. For example, parameter 0404 stores the motor speed at the time of the fault.

Maintenance Maintenance WARNING Read Safety on page 1-3 before performing any maintenance on the equipment. Ignoring the safety instructions can cause injury or death. Maintenance Intervals If installed in an appropriate environment, the drive requires very little maintenance. This table lists the routine maintenance intervals recommended by Daikin.
Maintenance Maintenance Figure 12: Drive Module Fan Replacement, R1–R4 Capacitors The drive intermediate circuit employs several electrolytic capacitors. Their life span is from 35,000…90,000 hours depending on drive loading and ambient temperature. Capacitor life can be prolonged by lowering the ambient temperature. It is not possible to predict a capacitor failure. Capacitor failure is usually followed by a input power fuse failure or a fault trip. Contact Daikin if capacitor failure is suspected.

Technical Data WARNING Relay coils generate noise spikes in response to steps in applied power. To avoid drive damage from such spikes, all AC relay coils mounted across drive inputs require R-C snubbers, and all DC relay coils mounted across drive outputs require diodes – see figure.
