Description:
Please input CE88󲕏 CE95 constants to proceed motor constant autotuning according to specification of
nameplate.
The low speed compensation of V/f curve were set by CE89 to apply to Rotational autotuning (CE88=0), V/f curve
will be modified after autotuning. Constant setting is the percentage of low speed star torque.
Select adjustment mode
1. Rotational mode autotuning (CE88=0)
Input specification of nameplate after set CE88=0. When the page of CE-88 constants were operated. The
function of autotuning will be processed by pressing FWD this moment, TunE is shown on screen. Motor data
is needed by autotuning when motor run. Pass will be shown after succeeded.
2. Stationary mode autotuning (CE-88=1)
Input specification of nameplate after set CE-88=1. When the page of CE-88 constants were operated. The
function of autotuning will be processed by pressing FWD this moment, TunE is shown on screen. Motor data
is needed by autotuning when motor run. Pass will be shown after succeeded. (Collocate with CE-95 motor
unload current setting)
3. Stationary autotuning for line-to-line resistance only (CE-88=2)
Autotuuning can beused to prevent controle errors when the motor cable is long or the cable length has
changed or when the motor and inverter have different capacities. When keypad is operated through the page of
CE-88 constants, press FWD to process autotuning decetion motor line-to-line resistor (Cd-78).
Notice: 1. The motor have to be disconnected from machine and a danger never occurs when Rotational mode
autotuning is implemented.
2. A machine does not allow motor spontaneously Rotational, please implement Stationary mode autotuning.
(CE-88=1)
3. Power will be supplied to the motor when Stationary mode autotuning and stationary for line-to-line
resistance are performed even though the motor will not turn. Do not touch the motor until autotuning has
been completed.
