2.7 H: Terminal Functions
172 YASKAWA ELECTRIC TOEP C710687 03B FSDrive-MV1000 Parameter Guide
Setting 1: LOCAL/REMOTE Selection
This setting allows the input terminal to determine if the drive will run in LOCAL mode or REMOTE mode.
Note: 1. If one of the contact input terminals is set to LOCAL/REMOTE, then the LO/RE key on the digital operator will be disabled.
2. When the drive is set to LOCAL, the will light.
3. The default setting of the drive is not to allow switching between LOCAL and REMOTE during run. To allow the drive to switch
between LOCAL and REMOTE during run, Refer to b1-07: LOCAL/REMOTE Run Selection on page 107.
Setting 2: External Reference 1/2 Selection
This function switches the Run command and frequency reference source between External reference 1 and 2 if the drive
is in REMOTE mode.
Note: With default settings the drive is not to allow switching between External reference 1 and 2 during run. Refer to b1-07: LOCAL/
REMOTE Run Selection on page 107 if this feature is required by the application.
Settings 3 to 5: Multi-Step Speed Reference 1 to 3
Switches multi-step speed frequency references d1-01 to d1-08 by contact inputs. Refer to d1-01 to d1-17: Frequency
Reference 1 to 16 and Jog Frequency Reference on page 140 for details.
Setting 6: Jog Reference Selection
The Jog frequency set in parameter d1-17 becomes the frequency reference when the input terminal closes. Refer to d1:
Frequency Reference on page 140 for details.
Setting 7: Accel/Decel Time Selection 1
Switches between accel/decel times 1 (C1-01 and C1-02) and 2 (C1-03 and C1-04). Refer to C1-01 to C1-08: Accel,
Decel Times 1 to 4 on page 128 for details.
Setting 8, 9: Baseblock Command (N.O): Baseblock when Closed
Baseblock command (N.C.): Baseblock when Open
When the drive receives a Baseblock command, the output transistor stops switching and the motor coasts to stop.
During this time, the alarm “bb” will flash on the digital operator to indicate baseblock. When baseblock ends and a Run
command is active, the drive performs Speed Search to get the motor running again.
WARNING! Sudden Movement Hazard. When using a mechanical holding brake with the drive in a lifting application, close the
brake when the drive output is cut off by a baseblock command triggered by one of the input terminals. Failure to
comply will result in a slipping load from the motor suddenly coasting when the baseblock command is entered and
may cause serious injury or death.

Status Description
Closed LOCAL: The frequency reference and Run command are input from the digital operator.
Open
REMOTE: The frequency reference and Run command are input from the external reference that has been selected. If a contact
input set to H1- = 2 is active, they will be read from external reference source 2 (b1-15 and b1-16). Otherwise they will be
read from external reference source 1 (b1-01 and b1-02).
Status Description
Open External reference 1 is used (defined by parameters b1-01 and b1-02)
Closed External reference 2 is used (defined by parameters b1-15 and b1-16)
