5.4 d: Reference Settings
YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual 185
■ Motor Switch Selection
When an input terminal selects motor 2 (H1- = 16), the drive will operate a second motor using V/f Control. The
drive cannot control motor 2 with OLV, CLV or CLV/PM.
The motor 2 speed reference in d1-27 can also be used to operate motor 1 using V/f Control. Refer to Table 5.8 for
combinations of selecting the speed reference for motor 2 and the motor 1/2 selection switch. (H1- = 53).
Table 5.8 Speed Reference for Motor 2, Controlling Motor 1 and 2
■ d1-27: Motor 2 Speed Reference
Sets the speed reference for motor 2.
Note: 1. The drive will control motor 1 when this parameter is set to 0.00.
2. Set the accel/decel times in parameters C1-12 and C1-13 when using motor 2.
3. When motor 2 is selected, the following monitors will display values in Hz: U1-01, U1-02, U1-05, U4-19, U4-20.
■ d1-28: Leveling Speed Detection Level
When the speed priority selection in d1-18 is set to “0” or “3” and the speed reference value falls below the level set in
d1-28, the drive interprets the selected speed as leveling speed. This parameter must be set to use the Speed Control Loop
setting 3 when d1-18 = 0/3. Refer to C5: Speed Control Loop on page 179 for details.
■
d1-29: Inspection Speed Detection Level
When the speed priority selection in d1-18 is set to “0” or “3” and the speed reference value is below the level set in d1-29
but higher than the level set in d1-28, the drive interprets the selected speed as inspection speed. This parameter must be
set to use the Inspection Operation function when d1-18 = 0/3. Refer to Inspection Operation on page 128 for details.
The value set to d1-27
<1> Enter the same values to the E3 and E4 parameters that are set for the E1 and E2 parameters.
