92 Functional description CG Drives & Automation 01-7492-01r1
Rotation [219]
Overall limitation of motor rotation
direction
This function limits the overall rotation, either to left or
right or both directions. This limit is prior to all other
selections, e.g.: if the rotation is limited to right, a Run-Left
command will be ignored. To define left and right rotation
we assume that the motor is connected U-U, V-V and W-W.
Speed Direction and Rotation
The speed direction can be controlled by:
• RunR/RunL commands on the control panel.
• RunR/RunL commands on the terminal strip
(terminals 1-22).
• Via the serial interface options.
• The parameter sets.
Fig. 91 Rotation.
In this menu you set the general rotation for the motor.
Remote Signal Level/Edge [21A]
In this menu you select the way to control the inputs for
RunR, RunL and Reset that are operated via the digital
inputs on the terminal strip. The inputs are default set for
level-control, and will be active as long as the input is made
and kept high. When edge-control is selected, the input will
be activated by the low to high transition of the input. See
chapter 7.2 Remote control functions page 67 for more
information.
Mains supply voltage [21B]
In this menu the nominal mains supply voltage connected to
the AC drive can be selected. The setting will be valid for all
parameter sets. The default setting, Not defined, is never
selectable and is only visible until a new value is selected.
This menu specifies the AC supply voltage. The
corresponding DC voltage is 1.34 times higher.
Once the supply voltage is set, this selection will not be
affected by the Load Default command [243].
Brake chopper activation level is adjusted using the setting
of [21B].
219 Rotation
Default: R + L
R1
Speed direction is limited to right
rotation. The input and key RunL are
disabled.
L2
Speed direction is limited to left rotation.
The input and key RunR are disabled.
R+L 3 Both speed directions allowed.
21A Level/Edge
Default: Level
Level 0
The inputs are activated or deactivated
by a continuous high or low signal. Is
commonly used if, for example, a PLC is
used to operate the AC drive.
Edge 1
The inputs are activated by a transition;
for Run and Reset from “low” to “high”
and for Stop from "high" to "low".
CAUTION!
Level controlled inputs DO NOT comply with
the Machine Directive if the inputs are
directly used to start and stop the machine.
NOTE: Edge controlled inputs can comply with the
Machine Directive (see the chapter 8. EMC and
standards page 73) if the inputs are directly used to
start and stop the machine.
WARNING!
This menu must be set according to the
AC drive product label and the supply
voltage used. Wrong setting might damage
the AC drive or brake resistor.
NOTE: The setting is affected by the “Load from CP”
command [245] and if loading parameter file via
EmoSoftCom.
