IPM motor control <IPM>
CAUTION
· For the setting range of a speed command under dedicated IPM motor (MM-EFS 1500r/min specification, MM-EF 1800r/min
specification) controls, refer to the output frequency range in Chapter 8.2 Common specifications (Refer to page 348).
· The selectable carrier frequencies under IPM motor control are 2k, 6k, 10k, and 14kHz.
· Constant-speed operation cannot be performed in the low-speed range lower than 150r/min (MM-EFS 1500r/min specification) or
180r/min (MM-EF 1800r/min specification). Generally, speed control can be performed in the range that satisfies the ratio, 1:10.
· During IPM motor control, the RUN signal is output about 100ms after turning ON the start command (STF, STR). The delay is
due to the magnetic pole detection.
· The following operations and controls are disabled during IPM motor control: adjustable 5 points V/F, bypass sequence,
energy saving operation, Optimum excitation control, and speed smoothing.
· The option surge voltage suppression filter (FR-ASF-H/FR-BMF-H) and sine wave filter (MT-BSL/BSC) cannot be used under
IPM motor control, so do not connect them.
· When parameter copy is performed from a FR-F700P series inverter, which is set to use MM-EFS under IPM motor control,
check that IPM motor control is selected on the operation panel (P.RUN is lit) after the copy. When parameters are copied to a
FR-F700P series inverter, which is not compatible with MM-EFS, Simple magnetic flux vector control is selected instead of IPM
motor control.
