B.2 Parameter Table u n: Advanced Performance Set-Up The n parameters are used to adjust more advanced performance characteristics. u o: Operator Related Parameters o parameters are used to set up the LED digital operator displays. 180 SIEP C710606 33A OYMC AC Drive – J1000 User Manual No. Name Description Range Def. Mode Addr. Hex Pg. n1: Hunting Prevention Use n1 parameters to configure hunting prevention operation. n1-02 Hunting Prevention Gain Setting Sets the gain for the Hunting Prevention Function. If the motor vibrates while lightly loaded, increase the gain by 0.1 until vibration ceases. If the motor stalls, decrease the gain by 0.1 until the stalling ceases.
0.00 to 2.50 1.00 O 581 111 n3: Overexcitation Braking Use n3 parameters to configure the overexcitation braking function. n3-13 Overexcitation Deceleration Gain Applies a gain to the V/f pattern during deceleration (L3-04 = 4). Returns to normal values after ramp to stop or at re-acceleration. To increase the braking power of overexcitation, increase the gain by 1.25 to 1.30. 1.00 to 1.40 1.10 O 531 111 No. Name Description Range Def. Mode Addr. Hex Pg. o1: Display Settings Use o1 parameters to configure the digital operator display. o1-02 User Monitor Selection After Power Up Selects the monitor to display upon power-up. 1: Frequency Reference (U1-01) 2: Forward/Reverse 3:
Output Frequency (U1-02) 4: Output Current (U1-03) 1 to 4 1 O 501 112 o1-03 Digital Operator Display Selection Sets the units to display the frequency reference and output frequency. 0: 0.01 Hz 1: 0.01% (100% = E1-04) 0, 1 0 O 502 112 o2: Operator Keypad Functions Use o2 parameters to configure LED digital operator key functions. o2-02 STOP Key Function Selection Determines if the STOP key on the digital operator will stop the drive when operating from the external terminals or via serial communication. 0: Disabled 1: Enabled 0, 1 1 O 506 112 o2-04 Drive Model Selection Sets the drive model. This parameter only needs to be set when installing a new control board.
Do not change for other reason. 0 to FF dep. on drive spec. O 508 112 o2-05 Frequency Reference Setting Method Selection Selects if the ENTER key must be pressed when inputting the frequency reference by the operator keypad. 0: Data/Enter key must be pressed to enter a frequency reference. 1: Data/Enter key is not required. The frequency reference is adjusted by the UP and DOWN keys. 0, 1 0 O 509 113 o2-06 Operation Selection when Digital Operator is Disconnected Sets drive action when the digital operator is removed in LOCAL mode or with b1-02 = 0 (valid for optional remote operator only). 0: The drive will continue operation 1:
The drive will trigger a fault (oPr) and the motor will coast to stop 0, 1 0 O 50A 113 o2-09 Initialization mode (Maker setting) 0 to 3 dep. on drive spec. O 50D 113 o3: Copy Function Use o3 parameters to Read, Copy and Verify the parameter settings to and from the drive. o3-01 Copy Function Selection Selects the copy function operation. 0: No action 1: READ - All parameters are read from the drive and stored in the LED operator. 2: COPY - All parameters are copied from the LED operator to the drive. 3: VERIFY - Parameter settings in the drive are compared to those in the LED operator. NOTE:
When using the copy function, the drive model number (o2-04) and the software number (U1-14) must match or an error will occur. 0 to 3 0 O 515 113 o3-02 Copy Function READ Permission Locks the READ operation to prevent accidental overwriting of the data stored in the LED operator. 0: READ operation prohibited 1: READ operation allowed 0, 1 0 O 516 113
