Instruction manual 91/104 V9.2
Commissioning
•
ENABLED: The function is activated. The drive can switch a set of parameters based on the selected range with the appro-
priate digital input (see section "Electronic gamma change“ on page 67).
Selected Gear
This menu only appears if the “Stage Function " function is activated and indicates which speed range is currently selected with the
digital input. The possible indications are as follows:
•
STAGE 0: The STAGE 0 parameter group that corresponds to the SLOW speed range is activated. The digital output will
also be controlled to activate the right contactor and controlled the actual closure.
•
STAGE 1: The STAGE 1 parameter group that corresponds to the speed range FAST is activated. The digital output will also
be controlled to activate the right contactor and controlled the actual closure.
Copy from Stage 0
This menu is used to copy parameters from the Stage 0 range (Slow Range) to the range that is currently selected.
To start copying the parameters from Stage 0 you have to follow these points:
1. Using the buttons on the front, reach the “Copy from Stage 0 " menu.
2. In the bottom line is the words “UP to confirm ". Press the "
►" button to enter the "change parameter" mode.
3. The
“
“ character
appears in the lower left
corner of the display. At this point press “▲” (i.e. UP).
4. Start the copying phase indicated by the inscription “Wait.... ". At the end appears the inscription “OK " indicating that the
operation is finished correctly.
5.
At this point, you can press “◄” to confirm and exit the
“Edit Parameter "
mode. The parameters of the currently selected
Stage (see “Selected Gear " Menu) were overwritten by those of Stage 0.
Check Contactors
This menu is used to enable the function to control the effective closing of the power switches on the connections of the motor. Nor-
mally this function is enabled to make it safer, but if the digital inputs are not available then you can turn it off but the user must make
sure that the drive is not enabled if the switches have not been closed. The possible selections are as follows:
•
DISABLED: Digital inputs with the “Check STAGE " function are not used and are therefore available for other functions.
The drive cannot know if contactors work regularly, so they must be checked by the PLC or CNC before enabling the drive.
•
ENABLED: Digital inputs with the “Check STAGE " function are used to control the effective closing of the switches for the
STAGE 0 or STAGE 1 connection. If this does not happen correctly, the drive does not enable and signals an alarm message
on the display.
Ext Torque Limit
Menu group with parameters to adjust the external torque limit function (see section "limit“ on page 70).
Torque Limit
This menu is used to enable the maximum torque limitation function provided by the motor. The possible selections are as follows:
•
DISABLED: The torque limit is fixed at the maximum value and cannot be modified from the outside.
•
ENABLED: The torque limit varies with a value proportional to the selected analogue reference or the value of the parameter
“Limit Setpoint ".
Limit Setpoint
Minimum Maximum Units of measure
0.0
+100.0
%
This parameter limits the torque delivered by the motor and can be changed manually using the LCD display and keypad, or can be
modified from the outside with a selectable analog input.
Limit Output
This menu indicates the current torque limit value as a percentage of the motor maximum. When the maximum torque limitation func -
tion is deactivated, this parameter remains fixed at 100 %, otherwise it indicates the currently valid limit value.
Anti Backlash
Menu group with parameters to enable and adjust the anti backlash function with two drives (see section "Anti-backlash system“ from
page 71).
AntiBack Mode
This menu is used to enable the “anti backlash” function and to select the drive mode: operation from “Master” motor or “Slave”
motor. The possible selections are as follows:
•
DISABLED: The “anti-backlash” function is disabled and the drive normally works as a single motor.
•
MASTER 1: The “anti-backlash” function TYPE 1 is active and the drive works as a MASTER motor. All references and
commands coming from the CNC or PLC will be connected to this drive.
