(2) Debugging and operation methods

Applicable scenarios for operating methods, tools/carriers, core processes

Software debugging MD_SHELL software (≥ 4.20 version) connects PC and controller → sets axis address → inputs motor parameters → automatically calculates control parameters → downloads effective system integration and batch configuration

Panel operation S1 button+7-segment digital tube short press S1 to view address → long press for 2 seconds to enter settings → adjust tens/units bit → confirm and save on-site quick address configuration and status viewing

External control binary/analog terminal (X21) terminal allocation function (such as enable, emergency stop, limit) → external signal triggering → operation monitoring industrial PLC linkage, automation production line

USS21A communication adapter enables software debugging and data transmission between PC and controller via RS-232/RS-485 connection

Installation and wiring specifications

(1) Mechanical installation requirements

Installation position: Fixed installation inside the switchgear, the power module and shaft module need to be tightly attached to the heat sink (35mm grid mounting hole)

Heat dissipation gap: Reserve ≥ 100mm heat dissipation space above and below, and the multi axis module heat sink needs to be grounded with copper bars/braided wires for conduction

Braking resistor: Installed on a well ventilated area (such as the top of a cabinet), avoiding proximity to thermal sensitive components, and the wire cross-section is adapted to the maximum braking current

(2) Key points of electrical installation

Wiring specifications: Power lines (L1/L2/L3, U/V/W) should be wired separately from signal lines, with a spacing of ≥ 20cm; encoder/rotary transformer cables should use twisted pair shielded wires (up to 100m in length), with both ends of the shielding layer grounded

EMC compliance: NF series filters are required for the input end, and HD00X output chokes can be selected for the output end; The distance between the filter and the controller is ≤ 400mm

UL compliance: Only use 60/75 ℃ copper wire, power terminal tightening torque of 3.5Nm (MKS is 1.5Nm), fuse specification ≤ 30A/600V

Fault diagnosis and maintenance

(1) Common faults and solutions

Fault code, fault type, typical cause, handling measures

F01 overcurrent motor short circuit, output stage fault troubleshooting cable short circuit, replace faulty module

F07 DC bus overvoltage brake resistor fault, short deceleration slope check brake resistor wiring, extend deceleration time

F14 rotary transformer fault cable breakage and poor shielding inspection of rotary transformer wiring, repair of shielding layer

F27 limit switch is missing and not connected, or the wiring is disconnected and connected to the limit switch, or X21.7/X21.8 is short circuited to 24V

(2) Maintenance points

Regular maintenance: Power on for at least 5 minutes every 2 years (when stored for a long time), clean the dust on the heat sink

Reset method: Supports power restart, terminal reset, software reset. Automatic reset requires enabling P630 parameter (default off)

Spare parts and services: If the fault cannot be resolved, please contact SEW Electronic Service Department to provide the equipment model, fault code, and application scenario
