VFD-M Series

5-54

Pr.106

Rated Slip

Factory Setting: 3.0

Settings 0.00 to 10.00 Hz Unit: 0.01Hz

 Example of Slip calculation: The rated speed of 4 poles/3 φ/ 60Hz/ 220V on the

nameplate is 1710RPM. The rated slip is then: 60-(1710/(120/P))=3Hz. (being P the

number of poles)

Pr.107

Vector Voltage Filter

Factory Setting: 10

Settings 5 to 9999 Unit: 2ms

Pr.108

Vector Slip Compensation Filter

Factory Setting: 50

Settings 25 to 9999 Unit: 2ms

 This parameter sets the low-pass filter in vector control.

 Example: Pr. 107 = 10 X 2ms =20ms, Pr. 108 = 50 X 2 ms =100ms.

Pr.109

Selection for Zero Speed Control

Factory Setting: 00

Settings 00 No output

01 Control by DC voltage

 This parameter is used to select the control method at zero speed. If set to 01, the

voltage in Pr.110 is used for holding torque.

Pr.110

Voltage of Zero Speed Control

Factory Setting: 5.0

Settings 0.0 to 20.0 % of Max. output voltage (Pr.05) Unit: 0.1%

 This parameter should be used in conjunction with Pr.109.

 Example: if Pr.05 = 100 and this parameter is set to 20.0, the level of output voltage is

100 X 20.0% = 20.

Pr.111

Deceleration S Curve Factory Setting: 00

Settings 00 to 07

 When this parameter is set differently to zero, it selects a deceleration S-curve and

overrides Pr.14. Otherwise, Pr.14 sets the deceleration S-curve.

Note: From the diagram shown below, the original setting accel/decel time will be for

reference when the function of the S-curve is enabled. The actual accel/decel time will

be determined based on the S-curve selected (1 to 7).
