Reducing Motor Speed Fluctuation (Slip Compensation Function) When the load is large, the amount of motor slip also grows large and the motor speed decreases. The slip compensation function controls the motor at a constant speed, regardless of changes in load.
Page 138 Adjusting Slip Compensation Gain Set C3-01 to 1.0 to compensate the rated slip set using the rated torque output status. Adjust the slip compensation gain using the following procedure. 1. Set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current) correctly. You can calculate the motor rated slip from the values on the motor nameplate using the following for- mula.

Troubleshooting Troubleshooting Due to constant setting errors, faulty wiring, and so on, the Matrix converter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures.
Page 189: If The Motor Does Not Operate
If the Motor Does Not Operate Use the following information if the motor does not operate. The motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Matrix converter is not in drive mode and the DRIVE indicator on the Digital Operator (JVOP-160) does not light up, the Matrix converter will remain in ready status and will not start.
Page 190: If The Direction Of The Motor Rotation Is Reversed
Troubleshooting The operation method selection is wrong. If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an exter- nal operation signal is input. Set b1-02 to 3 (PLC) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital Operator operation.
Page 191: If The Motor Does Not Put Out Torque Or If Acceleration Is Slow
If the Motor Does Not Put Out Torque or If Acceleration is Slow Use the following information if the motor does not output torque or if acceleration is too slow. The torque limit has been reached. When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This can cause the torque to be insufficient, or the acceleration time to be too long.
Page 192: If There Is Low Speed Control Accuracy At High-Speed Rotation In Open-Loop Vector Control Method
Troubleshooting If There is Low Speed Control Accuracy at High-speed Rotation in Open- loop Vector Control Method The motor's rated voltage is high. The Matrix converter's maximum output voltage is determined by its input voltage. (For example, if 3300 VAC is input, then the maximum output voltage will be 3300 VAC.) If, as a result of vector control, the output voltage reference value exceeds the Matrix converter output voltage maximum value, the speed control accu- racy will decrease.

Reset the gain to a more effective level by adjusting constants C4-02 (torque compensation time constant), n2-01 (Speed feedback detection control (AFR) gain), and C3-02 (Slip Compensation Primary Delay Time) in order.
Page 194: If Output Frequency Does Not Rise To Frequency Reference
Troubleshooting If Output Frequency Does Not Rise to Frequency Reference Use the following information if the output frequency does not rise to the frequency reference. The frequency reference is within the jump frequency range. When the jump frequency function is used, the output frequency does not change within the jump frequency range.

Page 196 Maintenance and Inspection The FSDrive-MX1S series Matrix converter is configured with many parts, and these parts must be oper- ating properly in order to make full use of the Matrix converter functions. For this reason, it is essential to catch early signs of any malfunction and take prompt corrective action by periodically inspecting the Matrix converter.
Page 197: Warranty Period
The warranty period of the FSDrive-MX1S series Matrix converter is explained below. Warranty Period: This product is guaranteed for twelve months after being delivered to the end user or, if applicable, eighteen months from the date of shipment from Yaskawa’s factory, whichever comes first. Daily Inspection Check the following items while the system is operating.
Page 198: Periodic Inspection
Periodic Inspection Check the following items during periodic inspections. Turn off the medium-voltage power supply, make sure that all LEDs on the front cover of the cell control board are unlit, and then wait at least 15 minutes before starting inspection. Touching terminals immediately after turning off the power supply may result in electric shock.

Page 200 The details of periodic inspections are described below. Megger Check (Measurement of Insulation Resistance) 1. Measure insulation resistance of the Matrix converter primary circuit. Use a 1000 V Megger insulation resistance tester. The measured insulation resistance must be 30 MΩ or more.
Page 201 Maintenance and Inspection Transformer Inspect the transformer as described below. 1. Check the external appearance 2. Retighten the bolts of transformer I/O terminals and primary voltage tap terminals 3. Measure the transformer secondary voltage. Turn on the control power supply and medium-voltage power supply, and measure the input voltages to the power cells as shown in Fig.
Page 202 Air Filter If the air filter is clogged with dirt and dust, the cooling capacity of the Matrix converter will be degraded, resulting in abnormal temperature rise. Check the air filter for dirt and dust at each daily inspection, and peri- odically clean it with neutral detergent.
Page 203: Periodic Maintenance Of Parts
Matrix converter maintenance periods are noted below for your reference. Refer to Page 8-13 for the replacement procedure for the cooling fan. For replacement of other parts, contact your Yaskawa representative. These replacements require trained pro- fessionals. Table 8.3 Part Replacement Guidelines...
Page 204: Spare Parts
Considering the importance of the system in which the FSDrive-MX1S series Matrix converter is used, it is recommended that spare parts be prepared in advance for all possible measures for maintenance management. Table 8.4 lists the recommended spare parts. Confirm the following items and contact your Yaskawa represen- tative when ordering the spare parts.

Page 210: Memory Backup Battery Replacement Procedure
Memory Backup Battery Replacement Procedure Replacement Period A battery for memory backup is provided in the controller. If the LED indicator lamp BAT ALM lights up, the battery voltage is low. Replace the battery. (We recom- mend replacing the battery every 5 years regardless of the indicator lamp status.) If the power supply is turned off while the BAT ALM is lit, the data and calendar settings stored in the mem- ory may be lost.
