Explanation of the parameters
Parameterization of MOVIPRO
®
Set the following parameters:
The motor protection function processes the utilization of the connected motors sep-
arately for both parameter sets. The motor protection function must not be used if
only one motor is permanently connected to the inverter and the "parameter set
changeover" function is only used for control purposes. Equally, the motor protection
function must not be used with group drives because it is not possible to protect each
individual motor reliably.
• One servomotor:
– Motor without KTY temperature sensor: The power section calculates and dis-
plays the motor utilization based on the current. The goal is to determine after only
a few cycles or during startup whether the drive is going to switch off due to an
overload with error "A1.F31" (TF trip). This setting is available for parameter set
1 only.
Requirements: Motor utilization is always determined based on the rated motor
current. Enter the duration of the machine cycle to receive an exact statement
concerning the utilization for the motor powering the machine cycle.
The following signal and display functions are available in conjunction with motor
protection:

Self-ventilation or forced cooling
Binary output can be programmed to:
/Motor utilization 1/2
Prewarning if motor utilization 1/2 exceeds a value of 100 %.
In this case, the programmed output is set to "0" = 0 V.
INFORMATION
Switching off the inverter (mains and 24 V external) always resets the motor utili-
zation to zero; any motor heating existing when the motor is switched back on is
not taken into account.
