Beijer Electronics BFI-H2 V1.12 - Manual (Page 41)

User Guide Revision 1.12

The function uses the Boost Voltage on the drive reaching zero speed in order to create a current and maintain an appropriate temperature
within the motor. The drive Standby Mode must be disabled so that the drive output is not automatically put into Standby following a period
of operation with zero speed reference.
The level of DC Injection Voltage applied to the motor is set in parameter P1-11 (V/F Boost Voltage). The current can be monitored by changing
the OLED display to show Amps (cycle the display to show Amps by pressing the Navigate button).
Caution: Always confirm the maximum acceptable current level that can be applied to the stationary motor prior to configuring the
voltage Boost function. It may be necessary to contact the motor manufacturer to confirm acceptable levels for operation. Check
operation of the drive to ensure current levels are within the specified limited.
The time set in the Standby Mode parameter (P2-27) must be 0. This will disable Standby Mode and ensure Boost Voltage is applied whilst the
drive is enabled with zero speed reference.
Ramp to Stop should be enabled (P1-05=0) and appropriate ramp rates set in P1-03 and P1-04.
If an input is required to activate motor stop with voltage boost then a digital input can be set to Preset Speed 1 (see section 10.1) and the
Preset Speed 1 value (P2-01) set to 0Hz.
Quick Setup Overview:
Setting up DC Injection braking on zero speed reference
 Set Basic parameters P1-01 to P1-10.

Ensure P1-05 is set to 0, Ramp to Stop. Ensure appropriate ramp rates are set in P1-03 and P1-04.
 Set Parameter P1-14 = 101 to allow access to advanced parameters in menu 2
 Set parameter P2-27 = 0 to disable drive Standby Mode (default)

If a digital input is required to activate motor stop with V/F Boost Voltage then ensure P1-13 is set to 1 (default). Digital input 2
(control terminal 3) is now configured for this function. Ensure P2-01 = 0.

Set the Boost Voltage to apply in P1-11.
 Monitor current levels on the drive display and motor temperature to ensure they remain within the motor manufacturers specified
limits.
