2.7 H: Terminal Functions
The diagram below illustrates how the DC Injection Braking function works.
Figure 2.49
Setting 61, 62: External Speed Search command 1, 2
These input functions can be used to enable Speed Search even if parameter b3-01 = 0 (no Speed Search at start).
Refer to Activating of Speed Search on page 105
on page 103 for more 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 63: Field Weakening
Enabled in V/f Control. When closed, Field Weakening is performed. For details,
Field Forcing on page 149.
Setting 67: Communication test mode
The drive has a built-in function for self-diagnosing serial communications operation. The test involves wiring the send
and receive terminals of the RS-485 port together. The drive transmits data and then confirms that the communications
are received normally. For details on the self-diagnosing function and its operation, refer to the FSDrive-MV1000
Instruction Manual (Manual No. EZZ010926).
Setting 6A: Drive enable
A contact input configured as "Drive enable" (H1-
the input is closed. When the input is open, the digital operator will display "dnE" to indicate that the drive is disabled.
If a Run command is enabled before the terminal set for "Drive enable" closes, then the drive will not run until the Run
command is input (i.e., a new Run command is required). If the input is opened while the drive is running, the drive will
stop according to the stop method set to b1-03
Setting 70: Drive enable 2
A contact input configured as "Drive enable 2" (H1-
until the input is closed. When the input is open, the digital operator will display "dnE" to indicate that the drive is
disabled.
If a Run command is enabled before the terminal set for "Drive enable 2" closes, then the drive will not run until the Run
command is input (i.e., a new Run command is required). If the input is opened while the drive is running, the drive will
stop according to the stop method set to b1-03
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. Refer to d5: Torque Control on page 144
Preparing a Wait Time When Switching Between Torque and Speed Control
d5-06 can set up a wait time between opening and closing the input terminal using a parameter in units of ms. 3 analog
input terminals holds the reference values when speed control/torque control switching signal changes during this wait
time. Be sure to switch the signals with external devices within this wait time. Refer to
Speed Control on page 147.
