Chapter 6. Function Description (I/O)
1.25) Spd/Trq Sel (Speed/Torque Control Transfer)
Speed and torque control can be switched using this function. This terminal input overrides the input from the keypad.
1.26) Use Max Torque (Maximum Torque Enable)
If this input is ON, the torque limit value of the speed controller is fixed to its maximum value. On the contrary, when
this input turns off, the value defined at CON_29 ~ CON_31 applies to torque limit value. This function disables the
inverter continous operation.
If this function is used continously, it may lead to damage to the motor and inverter. Take caution when using this
function.
1.27) Use Trq Bias (Torque Bias Enable)
If one of the multi-function terminals (P1 ~ P7) is selected as “Use Trq Bias”, torque bias value is fed into the inverter
following the input signal. Besides, if “Use Trq Bias” is not set, and ‘Keypad’ is set at CON_32, torque bias value set at
CON_33 is fed into the inverter. And, if
“
Analog
”
is set at CON_32 (Trq Bias Src), and the input is selected as “Torque
Bias”, the torque bias value is fed into the inverter. Therefore, in order not to use the torque bias value, ‘None’ should be
set at CON_32 or one of the multi-function terminals (P1 ~ P7) should be selected as “Use Trq Bias” and then be kept
the terminal Open.
2) I/O_08 (Reversal of Multi-function input terminal)
Multi-function input terminal is based on the ‘A’ contact operation. If a specific terminal should be changed to ‘B’
contact operation, the relevant terminal setting should be set from ‘0’ to ‘1’, Once the relevant terminal is set to ‘1’, the
terminal operates on the basis of ‘B’ contact and it is effective before it is changed to ‘0’. But, in case of the external trip
‘B’ contact, it is changed to ‘A’ contact operation. Terminals are displayed in the order of P1, P2, P3, P4, P5, P6 and P7
from the beginning.
(P1 ~ P7: A contact) (P1, P6: B contact)
3) I/O_09 (Low Pass Filter Time Constant for the Terminals)
This setting affects the response speed of the control circuit terminals (FX, RX, BX, P1 ~ P7, RST). It is greatly
effective when electro-magnetic noise signal is present in the input signal. The larger the time constant becomes, the
slower response speed becomes. Response speed is approximately proportional to the setting value times 2.5 [m sec].
