Example of Slip calculation:
The rated speed of 4 poles/3 / 60Hz/ 220V on the nameplate is 1710
RPM. The rated slip is then: 60-(1710/(120/P))=3Hz. (being P the number
of poles)
Vector V oltage Filter
P 107
Settings
5 to 9999
Vector Slip Compensation Filter
P 108
Settings
25 to 9999
This parameter sets the low-pass filter in vector control.
Example: P107 = 10
2ms =20ms, P108 = 50
Selection for Zero Speed Control
P 109
No output
00
Settings
01
Control by DC voltage
This parameter is used to select the control method at zero speed. If
set to 01, the voltage in P110 is used for holding torque.
Voltage of Zero Speed Control
P 11 0
Settings
0.0 to 20.0 % of Max. output voltage (P05)
This parameter should be used in conjunction with P109.
Example: if P05 = 100 and this parameter is set to 20.0, the level of
output voltage is 100 20.0% = 20.
P 111
Deceleration S Curve
Settings
00 to 07
When this parameter is set differently to zero, it selects a deceleration
S-curve and overrides P14. Otherwise, P14 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).
P 11 2
External Terminal Scanning Time
Settings
01 to 20
This function screens the signal on I/O terminals for CPU malfunctions
due to external transients. A setting of 02, makes the scanning time to
be 2
2 = 4 msec. Set P77 to 02 before changing settings in P112.
P 11 3
Restart Method after Fault (oc, ov, BB)
00
None speed search
Settings
01
Continue operation after fault speed search from speed reference
02
Continue operation after fault speed search from Minimum speed
This parameter is used to select the restart method after certain faults.
eg:over current over voltage and BB.
