frequency), easing an accelera-

tern has an effect on the preven-
tion of cargo collapse, etc.
Backlash compensation for reduction gear, etc.
Set " 3 " . This function stops the output frequency change tem-
porarily during acceleration/deceleration, reducing a shock
(backlash) generated when a reduction gear backlash is elimi-
nated suddenly. Use Pr.
33
to 36 for the setting.

Note: When Pr. 29
= 3,
Pr. 33 to 36 act as parameters for backlash
compensation function. Frequency jump function, if used, for
Pr. 33 to 36 will still function but parameter values are not
shown. To read these parameters set Pr. 29 = 0, 1 or 2.

and used wi'ih t'he inverter, the inverter must be protection-
coordinated with the high power factor converter. When
connecting the high power factor converter, always set any
of 3, 4 and 5 in Pr. 30. Also, connect cables between the
inverter, power supply and high power factor converter
correctly in accordance with the high power factor con-
verter instruction manual.
(1) lnverter operation enable signal input terminal
The inverter operation enable (RDY) signal of the high
power factor converter is entered into this terminal. Allocate
the used terminals to the MRSIAUIRT terminal by parame-
ter setting and connect it to the RDY terminal of the high
power factor converter (refer to Table 1). The conventional
functions of the used terminals are deleted (refer to Table
2).
