• Please don’t check the signal on PCB when inverter is running. • Parameters have already been set when ex-work, please don’t adjust it casually. 6．Keyboard Operation 6.1 LCD and operation Key (B800 Series without potentiometer) (B800-1 Series with potentiometer) -
Page 10: Utility Of Operation Key
6.2 Utility for operation key •When inverter ex-work, standard parameters are set as default. •Press “Enter” key one second, then enter into check/modify standard parameter group. •Press key to check the parameter group from F-01 to F-14 •Press “Enter” key again, which can read parameter value. - Page 11 If user want the motor stops work automatically (inertia stopping), please sets F-05 to 1. •V/F curve select F-06. General loading F-06=0. Such as fan, water pump etc. which are belonging to variable torque loading, Pls set F-06=1, which will reduce the energy wastage when motor run at low speed.

Page 20: Parameter Explanation
•Under keyboard operating mode, as F-12=1 or 2 and F-19=6, the rotary direction is controlled by multi-functions contact 3, which means the inverter can be started in reverse direction under the mode of keyboard operation. •Under keyboard operating mode, as F-12=1 or 2 and F-19=7, multi-function contact 2 and 3 “ON”... - Page 21 •F-06 V/F characteristic curve select. Either V=kf (linear) or V=kf (pumps/fans with HVAC rating). Note when F-06 is set to 1, the ramps are automatically set to 60s. (A) Relation between voltage and frequency. Pls. refer to picture: 0 curve is constant torque, 1 curve is variable torque.
