H2: Multi-Function Digital Outputs - YASKAWA T1000A Technical Manual

5.7 H: Terminal Functions
Setting 71: Speed/Torque Control switch
Switches the drive between Torque Control and Speed Control. Torque Control is enabled when the terminal is closed,
and Speed Control is enabled when the terminal is open. Note that parameter d5-01 must be set to 0 when using this
function. See d5: Torque Control on page 158
Setting 72: Zero Servo
Used to activate the Zero Servo function that can be used to lock the rotor at a certain position. Refer to
on page 139 for details.
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. See
1, 2 / ASR Integral Time 1, 2 on page 148
Setting 78: External torque reference polarity inversion
Reverses the direction of the torque reference when the terminal closes. Refer to
Setting the Torque Reference, Speed Limit, and Torque Compensation Values on page 158
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. Parameter b2-18 can be used to limit the
current during Short Circuit Braking.

Setting 7D (N.C.)
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.
