Setting 7A, 7B: KEB Ride-Thru 2 (N.C., N.O.)
An input terminal set to 7A or 7B can trigger Single Drive KEB Ride-Thru during deceleration. If enabled, L2-29 is
disregarded. Refer to KEB Ride-Thru Function on page 275
Digital Input Function
Setting 7A (N.C.)
Setting 7B (N.O.)
Note: KEB Ride-Thru 1 and 2 cannot both be assigned to the input terminals at the same time. Doing so will trigger an oPE3 error.
Setting 7C, 7D: Short Circuit Braking (N.O., N.C.) (OLV/PM, AOLV/PM)
An input programmed for this function can be used to activate Short Circuit Braking in Open Loop Vector control modes
for PM motors. By linking all three phases of a PM motor, Short Circuit Braking creates a braking torque that can be used
to stop a rotating motor or prevent a motor from coasting due to external forces (such as the windmill effect in fan
applications). Parameter b2-18 can be used to limit the current during Short Circuit Braking.
DIgital Input Function
Setting 7C (N.O.)
Setting 7D (N.C.)
Setting 7E: Forward/reverse detection
Determines the motor rotation direction for V/f Control with Simple PG feedback or V/f Control with PG feedback when
F1-21 (PG 1 Signal Selection) or F1-37 (PG 2 Signal Selection) are set to 0 (A Pulse Detection). 
If the input is open, the speed feedback signal is considered to be forward. If the input is closed, it is considered to be in
reverse. Refer to H6: Pulse Train Input/Output on page
Setting 7F: Bi-Directional PID Output Selection
If PID output to bi-directional output conversion is enabled in parameter d4-11, a digital input programmed for 7F can be
used to switch between normal output or bi-directional output. If the digital input is open, the PID output builds the out-
put frequency reference.
If the input is closed, the PID output is converted to bi-directional output frequency reference. Refer to
Bi-Directional Output Selection on page
Setting 90 to 97: DriveWorksEZ Digital Input 1 to 8
These settings are for digital inputs functions used in DriveWorksEZ. Normally there is no need to change these settings.
Setting 9F: DriveWorksEZ Disable
This function is used to enable or disable a DriveWorksEZ program in the drive. An input programmed for this function
is effective only if A1-07 = 2.
