Initialization Set-up
Parameter Access Level (A01-01)
This parameter allows the “masking” of parameters according to user level. See the following table:
Table 4-1: Parameter Access Level Settings
Control Method Selection (A01-02)
Select the control method best suited for your application.
Table 4-2: Control Method Selection Settings
NOTE: An auto-tune should be performed for all Flux Vector and Open Loop Vector applications.
Refer to the Auto-Tuning section on page 4-17.
Setting Description
0 Operation Only Access to only parameters A01-01, A01-06, and all U monitor parameters.
1
User Parameters Accesses parameters selected by OEM or installer (A02-01 to A02-32).
These User Parameters can be accessed using the Setup Mode of the digital operator.
2
Advanced Level For advanced programming in special applications. All parameters can
be viewed and edited.
Setting Description Model
0
V/f Control for Induction Motors (V/f)
Use this mode for simple speed control and for multiple motor applications with low
demands to dynamic response or speed accuracy. This control method is also used
when the motor parameters are unknown and Auto-Tuning cannot be performed. The
speed control range is 40:1.
G+
2
Open Loop Vector Control (OLV)
Use this mode for general, variable-speed applications that require precise speed
control, quick torque response, and high torque at low speed without using a speed
feedback signal from the motor (a speed control range of 200:1).
G+
3
Flux Vector Control (FLV)
Use this mode for general, variable-speed applications that require precise speed
control down to zero speed, quick torque response or precise torque control, and a
speed feedback signal from the motor. The speed control range is up to 1500:1.
