Setting 61, 62: External Speed Search Command 1, 2
These input functions enable Speed Search even when parameter b3-01 is set to 0 (no Speed Search at start).
Refer to Activating of Speed Search on page 111
on page 110 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 154.
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
Instructions (Manual No. TOEP C710687 02).
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 149
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 152.
Setting 73: Door Switch NC
The switch is closed if the drive panel door is closed. The dO fault occurs if the door is opened while the main power
supply is turned on.
Note: 1. This setting is available from the drive software versions S0108 and later.
2. Make sure to input the door switch signal to the contact inputs.
Setting 75, 76: Up 2, Down 2 Command
The Up 2 and Down 2 function adds a bias to the frequency reference. The input programmed for 75 (Up 2 function) will
increase the bias and the input programmed for 76 (Down 2 function) will decrease it.
Down 2 function works depending on the frequency reference source and parameters d4-01, d4-03, and d4-05. Refer to
d4: Frequency Reference Hold and Up/Down 2 Function on page 144
Down 2 related 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.
