Disable write EEPROM
function
When this function is enabled, you can’t write into EEPROM.
39
Torque command
direction
When Pr.07-13=2 and analog input is ACI or unipolar AUI, torque
command direction is decided by this terminal.
40 Enable drive function
When this function is enabled, the drive function can be executed. This
function can be used with multi-function output (setting Pr.02-11~Pr.02-
14 to 15) and (Pr.02-31 and Pr.02-32).
41
Detection of magnetic
contactor
This terminal is used for the feedback signal of magnetic contactor
ON/OFF.
When drive receives RUN command, the corresponding output terminal
(setting 15) will be enabled after Pr.02-31 time. It will check if this
function is enabled within the detection time (Pr.02-36). If NOT, the fault
of mechanical brake occurs and fault code “MCF” will be displayed.
42 Mechanical brake
When drive receives RUN command, the corresponding output terminal
(setting 12) will be enabled after Pr.02-29 time. It will check if this
function is enabled within the detection time (Pr.02-35). If NOT, the fault
of mechanical brake occurs and fault code “MBF” will be displayed.
43 EPS function
If power is cut during running, the drive will stop when DC bus voltage is
less than low voltage level. After power is cut, drive will run by the
frequency depend on EPS when EPS is applied and this function is ON.
