12.8 H: Terminal Function Selection
644 YASKAWA SIEPC71061753C GA500 Technical Manual
■ 76: Down 2 Command
Setting Value Function Description
76 Down 2 Command
Sets the function to decrease the frequency reference bias value to decelerate the motor when the terminal is activated. Set this
function and H1-xx = 75 [Up 2 Command] together.
When you activate the terminal set for Up2 Command, the bias will increase. When you activate the terminal set
for Down 2 Command, the bias will decrease. When you activate or deactivate the two commands, the drive will
hold the frequency reference.
Note:
• When you use this function, set the optimal bias limit values with d4-08 and d4-09 [Up/Down 2 Bias Upper Limit/Lower Limit].
• Refer to d4: Frequency Ref Up/Down & Hold on page 574 for more information.
■ 77: ASR Gain (C5-03) Select
Setting Value Function Description
77 ASR Gain (C5-03) Select
Sets the function to switch the ASR proportional gain to C5-01 [ASR Proportional Gain 1] or C5-03 [ASR Proportional Gain
2].
ON : C5-03
Switches the proportional gain to C5-03 [ASR Proportional Gain 2].
OFF : C5-01
Switches the proportional gain to C5-01 [ASR Proportional Gain 1].
Note:
Refer to C5: Auto Speed Regulator (ASR) on page 557 for more information.
■ 78: Analog TorqueRef Polarity Invert
Setting Value Function Description
78 Analog TorqueRef Polarity
Invert
Sets the rotation direction of the external torque reference.
ON : External torque reference reverse direction
OFF : External torque reference forward direction
■ 7A: KEB Ride-Thru 2 Activate (N.C.)
Setting Value Function Description
7A KEB Ride-Thru 2 Activate
(N.C.)
Sets operation of the KEB2 function through the KEB Ride-Thru 2 (N.C.).
ON : Normal operation
OFF : Deceleration during momentary power loss
When KEB Ride-Thru 2 is input, the drive will use Single Drive KEB Ride-Thru 2 for KEB operation. The L2-29
[KEB Method Selection] setting will not have an effect.
Note:
• If you set KEB Ride-Thru 1 [H1-xx = 65, 66] and KEB Ride-Thru 2 [H1-xx = 7A, 7B] at the same time, the drive will detect oPE03
[Multi-Function Input Setting Err].
• Refer to KEB Ride-Thru Function on page 697 for more information.
■ 7B: KEB Ride-Thru 2 Activate (N.O.)
Setting Value Function Description
7B KEB Ride-Thru 2 Activate
(N.O.)
Sets operation of the KEB2 function through the KEB Ride-Thru 2 (N.O.).
ON : Deceleration during momentary power loss
OFF : Normal operation
When KEB Ride-Thru 2 is input, the drive will use Single Drive KEB Ride-Thru 2 for KEB operation. The L2-29
[KEB Method Selection] setting will not have an effect.
