A: EC160 integrated machine is fitted with the synchronous master, but the user adopts Heidenhain 1387 rotary encoder in the line sequence of Monarch integrated machine. Recently, the line sequence of EC160 is consistent with that of SIEI inverter and STEP integrated machine and positive to No.10 line C+ and No.11 line C- of Monarch integrated machine.
Solution: After changing the parameter P3.12 from 0 to 1, Heidenhain 1387 rotary encoder in the line sequence of Monarch can be used. Save the parameter after modification, power off and reset EC160. The parameter is valid only when software version of main board ≥ 1.07 and DSP software version ≥ 1.01.
Note: If EC160 adopts the encoder line sequence of Monarch, the master can succeed in non-load autotuning, it can run in low speed and monitoring output current is normal. However, after running 5 times, 132 fault (large speed deviation) may occur once.
