V/Hz, Open Loop Vector or
Rotor Flux Control (RFC)
With the Commander GP20 many basic applications
can be up and running in minutes in the standard V/Hz
mode, but for applications with demanding speed torque
requirements or high inertial loads, Open Loop Vector
and the newly developed Rotor Flux Control modes are
available to boost shaft performance. Rotor Flux Control
provides near closed loop performance without requiring
encoder feedback. RFC is easy to configure using CTSoft
or keypad controls.
Plain Text, Multi-lingual Keypad
The Commander GP20 has a full-function data display
can be either mounted on the drive or remotely
mounted. The CGP-Keypad-Plus supports five languages,
plus a custom text database, which allows users to
customize parameter names to their own terminology. It
also possesses one-touch online help, and clearly marked
HMI controls. This keypad is “hot-pluggable,” enabling
it to be moved from one drive to another without
powering down.
GP20 SmartCard
The SmartCard is a revolution in
simplicity, allowing users to store
parameters and/or download stored
parameters to a drive, or dozens of
drives. This is a standard feature that
enables simple configuration of parameters in a variety of
ways is supplied free with each Commander GP20.
Note: Motor horsepower ratings are based on typical motor current ratings. Actual motor currents should be checked before selecting a particular drive. For
some high efficiency motors, the required full load motor current may allow the selection of a smaller drive than is indicated in the chart. The same consideration
would also apply for motors with less common power or voltage ratings.
Normal Duty
Suitable for most applications, current overload is set
at 110% for 60 seconds. Where motor rated current
is less than the drive rated continuous
current, higher overloads are achieved.
Heavy Duty
Suitable for demanding applications, current overload
is set at up to 175% for 40 seconds (150% on size
6). Where motor rated current is less than the drive
rated continuous current, higher overloads (200% or
greater) are achieved.
1) Size 6 drives require a +24VDC - 3.5A power supply for the heat sink fans not provided with unit. See the Options & Accessories section for available power supplies.
