parameters.
Note: 1. The Up 2 and Down 2 functions must be set as a pair.
2. When using the Up 2 and Down 2, set appropriate bias limit values to parameters d4-08 and d4-09.
Table 5.39 Up/Down 2 Operations
Setting 77: ASR gain switch
Switches the ASR gain between the values set to C5-01 and C5-03. The gain set to C5-03 is enabled when the terminal is
closed, and C5-01 is enabled when the terminal opens again. Refer to C5-01, C5-03/C5-02, C5-04: ASR Proportional
Gain 1, 2 / ASR Integral Time 1, 2 on page 224 for a more detailed description.
Setting 78: External torque reference polarity inversion
Reverses the direction of the torque reference when the terminal closes. Refer to d5: Torque Control on page 238 and
Setting the Torque Reference, Speed Limit, and Torque Compensation Values on page 239 for details.
Setting 7E: Forward/reverse detection (for V/f Control with Simple PG Feedback)
When a digital input is programmed for this function, the input determines the motor rotation direction for V/f Control
with Simple PG feedback (A1-02 = 0 and H6-01 = 3). 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 293.
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.

reference plus d4-03 (bias is increased for d4-03).
• When Down 2 is enabled, drive decelerates down to the
frequency reference minus d4-03 (bias is decreased for d4-03).

accel/decel, bias value is held until the output frequency meets
the reference (speed agree).

If the bias is constant for 5 s, it is saved to
parameter d4-06. The frequency reference
cannot be overwritten, so only the bias is
saved.
