Phantom Stop
The Phantom Stop allows quick identification of a faulted drive while stopping other drives with
Phantom Stop enabled. The Phantom Stop feature is designed to stop the drive operation using the
stopping method selected in C03-10 when a Phantom Fault input (H01-01–H01-08 = 5F or 63) is
active. The drive will indicate a Phantom Fault has occurred by blinking the LED on the RUN key in
sequence of two short bursts. The drive will resume normal operation when a Phantom Fault is
removed.

NOTE:
For settings of 0 or 2 deceleration is by B05-08.
Load Sharing/Torque Following - 2 or more mechanically coupled
motors
The Load Share Limit function allows the drive to follow the limit switch frequency references and
stopping methods when enabled.
Table 5-20: Load Share Limit Parameter Settings
The VG+ Series 4 Software allows one or more IMPULSE
®
•VG+ Series 4 driven motors to be
connected in a Master/Slave fashion such that slave inverter will follow the torque reference of the
master inverter. It can be configured in two ways, either as a dedicated Slave or as a Master/Slave
that can be switched on or off by multi-function digital input. When it is in Load Share Mode (Slave),
it is essentially a torque helper to the master motor. The Master outputs the commanded amount of
torque from a ± 10 VDC analog signal into the Slave, which correlates directly to the direction and
quantity of torque the Slave should apply to its own motor. This can be particularly useful when two
or more motors are driving a common load (i.e. single drum, gear box, etc.) and it is important that
they share the load. This will allow one inverter/motor to handle the speed reference and speed
regulation while the others simply help the master. This overcomes inherent problems with having
more than one inverter/motor trying to regulate speed on a common load. The Load Sharing function
can be used when the master is configured for Hoist or Traverse motions (i.e. for a hoist motion, two
or more motors coupled to a single gearbox; for a traverse motion, a circular crane, multiple motors
driving a single end truck, cable reel, etc).
NOTE:
The master drive can be an IMPULSE

•VG+ Series 1, 2, 3, or 4.
When using Multi-function digital input H01-0x = 66—”Load Share” (Torque Following mode), setting
C03-11 =
Enabled
will allow the inverter to accept the Limit Switch inputs where H01-0x = 06–0D.
When C03-11 =
Disabled
(Factory Default), the Slave will ignore any change in state of the Limit
switch inputs. The setting of this parameter is only in effect when the Multi-function digital input H01-
0x = 66 “Load Share” is
ON
. It is important to understand that when in Load Sharing mode, the Slave
is only supplying torque to help the Master. The Master typically handles the logic of limit switches or
