5.7 H: Terminal Functions
Setting 44/45/46: Offset Frequency 1/2/3 Addition
These inputs can be used to add offset frequencies d7-01, d7-02, and d7-03 to the frequency reference.
d7-03: Offset Frequency 1 to 3 on page 167
Setting 47: Node Setup
If the SI-S3/V option unit is connected, closing this terminal sets a node address for operation on a CANopen network.
Setting 60: DC Injection Braking
When a DC Injection Braking command is input while the drive is stopped, DC Injection Braking operation is activated. When
a Run command or a Jog command is input, DC Injection Braking is released.
128 for details on setting up the DC braking function.
The diagram below illustrates the DC Injection Braking function.
Setting 61/62: Speed Search 1/2
These input functions can be used to enable Speed Search even if parameter b3-01 = 0 (no Speed Search at start.
Activation of Speed Search on page 132
If b3-24 is set to 0 and b3-01 is set to 0, when the input terminal set for Speed Search 1 (H1-oo = 61) is enabled, Speed
Search will begin looking for the motor speed from the maximum output frequency. If the Speed Search 2 input (H1-oo =
62) is enabled, Speed Search starts looking for the motor speed starting at the frequency reference.
Search on page 130 for more information about Speed Search.
Note: Operator error oPE03 will result if both Speed Search 1 and Speed Search 2 are set to the input terminals at the same time.
Setting 65/66: KEB Ride-Thru 1 (N.C.)/2 (N.O.)
A digital input programmed for this function can be used to activate the KEB 1 function and detect power supply return.
Description
KEB 1 deceleration
Normal operation
Refer to Kinetic Energy Backup (KEB) Function on page 219
Setting 67: Communication Test Mode
The drive has a built-in function for self-diagnosing the serial communications operation. The test involves wiring the send
and receive terminals of the RS-485/RS-422 port together. The drive transmits data and then confirms the communications
are received normally. Refer to Self-Diagnostics on page 461
Setting 68: High Slip Braking
Closing an input programmed for this function triggers High Slip Braking. Once HSB is started, the drive has to completely
stop and the HSB input has to be removed before a restart can be performed.
Overexcitation Deceleration on page 241
Setting 6A: Drive Enable
A digital input configured as a Drive Enable input (H1-oo = 6A) will prevent the drive from executing a Run command until
the input is closed. When the Drive Enable input is open, the digital operator will display "dnE" to indicate that the drive is
disabled.
