Short description of important startup steps
Startup
5.5.3
Restoring the factory settings (P802)
You can use
P802 factory setting
to restore the factory setting stored in the EPROM for
almost all parameters.
5.5.4
Adjusting the PWM frequency (P86x)
P860 / P861
allows you to set the nominal cycle frequency at the inverter output. If
P862
/ P863
is set to "off", the cycle frequency may vary automatically depending on the unit
utilization.
5.5.5
Parameterizing the inverter address (SBus / RS485 / fieldbus) (P81x)
P810
sets the address of MOVITRAC
®
B for communication via serial interface.
5.5.6
Setting the control mode (P700)
This parameter is used to set the basic operating mode of the inverter. Setting on the
operator terminal.
V/f characteristic
curve (standard)
The default operating mode setting is V/f. Use this operating mode if you have no par-
ticular requirements on the speed quality and when a maximum output speed of 150 Hz
is required.
VFC characteristic
curve (vector con-
trol)
Start up the inverter in operating mode VFC or VFC & DC braking for the following re-
quirements:
• High torque
• Continuous duty at low frequencies
• Accurate slip compensation
• More dynamic behavior
For this purpose, you will have to choose the VFC or VFC & DC brake operating modes
from P01 at startup.
5.5.7
Application type specification
Speed control
Hoist
The hoist function automatically provides all functions necessary for operating an unbal-
anced hoist. For safety reasons, make sure to activate monitoring functions that prevent
the drive from starting.
DC braking
DC braking means the asynchronous motor brakes by using current injection. The motor
brakes without a braking resistor on the inverter.
Flying start func-
tion
The flying start function lets you synchronize the inverter to a motor that is already in
operation. This function is used in particular with drives that are not braked actively, run
on for a long time or are turned by a flowing medium, e.g. pumps and fans. The maxi-
mum flying start time is approx. 200 ms.
5.5.8
Selection of operating mode (4-quadrant operation P82x)
P820 / P821
allows you to enable and disable 4-quadrant operation. 4-quadrant opera-
tion is possible if you connect a braking resistor to MOVITRAC

B.
