P4-09 Regenerative Torque Limit
0.0
500
100
%
Active only in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1). Sets the maximum regenerating torque allowed by
the BFI drive.
P4-10
V/F Characteristic Adjustment Frequency
0.0
P1-09
0.0
Hz
When operating in V/F mode (P4-01 = 2), this parameter in conjunction with P4-11 sets a frequency point at which the voltage set in
P4-11 is applied to the motor. Care must be taken to avoid overheating and damaging the motor when using this feature.

Used in conjunction with parameter P4-10.

All BFI drives feature electronic thermal overload protection for the connected motor, designed to protect
the motor against damage. An internal overload accumulator monitors the motor output current over time,
and will trip the drive if the usage exceeds the thermal limit. When P4-12 is disabled, removing the power
supply from the drive and re-applying will reset the value of the accumulator. When P4-12 is enabled, the
value is retained during power off.

U,V,W
Stand motor phase sequence. Typically, this provides clockwise rotation of the motor.
1

Trip
When the overload accumulator reaches the limit, the drive will trip on It.trp to prevent damage to the motor.

Current
Limit
Reduction
When the overload accumulator reaches 90% of, the output current limit is internally reduced to 100%
of P1-08 in order to avoid an It.trp. The current limit will return to the setting in P4-07 when the overload
accumulator reaches 10%.

In this mode, when the drive functions as a Master in Master-Slave Mode, the data broadcast on the drive
network is the Master Actual Speed and the Master Torque Reference. This mode is suitable for Master-
Slave applications which required speed following.

8.3. Parameter Group 5 – Communication Parameters
8.3.1. Overview
Beijer BFI-P2 provides many methods to allow the user to connect to a variety of fieldbus networks. In addition, connection to options
such as external keypads, PC and BFI Copy Stick are possible. Parameter Group 5 provides the parameters required to configure the
various fieldbus interfaces and connection points.
8.3.2. Connecting Beijer Electronics Options
All Beijer Electronics options which require communication with the drive, such as the Remote Keypad options and BFI Copy Stick
connect to the Beijer BFI-P2 using the built in RJ45 connection point. The pin connections on these options are already matched, such
that a simple pin to pin plug in cable can be used to connect these options without any special requirements.
For further information on connecting and using these optional items, refer to the specific option User guide.
