CG Drives & Automation,01-5326-01r5
Functional Description
99
Set the nominal asynchronous motor speed.
Communication information
When the nominal speed of the motor is
≤
500 rpm, the
additional menu for entering the number of poles, [226],
appears automatically. In this menu the actual pole number
can be set which will increase the control accuracy of the AC
drive.
Communication information
Motor Cos
ϕ
Set the nominal Motor cosphi (power factor).
Communication information
Parameter for setting the type of motor ventilation. Affects
the characteristics of the I
2
t motor protection by lowering
the actual overload current at lower speeds.
Communication information
When the motor has no cooling fan, None is selected and
the current level is limited to 55% of rated motor current.
With a motor with a shaft mounted fan, Self is selected and
the current for overload is limited to 87% from 20% of
synchronous speed. At lower speed, the overload current
allowed will be smaller.
When the motor has an external cooling fan, Forced is
selected and the overload current allowed starts at 90% from
rated motor current at zero speed, up to nominal motor
current at 70% of synchronous speed.
Fig. 94 shows the characteristics with respect for Nominal
Current and Speed in relation to the motor ventilation type
selected.

WARNING!
Do NOT enter a synchronous (no-load)
motor speed.
NOTE: Maximum speed [343] is not automatically
changed when the motor speed is changed.
NOTE: Entering a wrong, too low value can cause a
dangerous situation for the driven application due to
high speeds.
