IMPULSE®•G+ & VG+ Series 4 Instruction Manual – February 2017
5-41
E-Lift (VG+)
The E-Lift (Emergency Lift) function can be utilized to operate the drive in the event of an encoder
related fault (PGO-1-S/PGO-1-H) that resulted from a defective encoder, encoder cable, or PG-X3
option card. E-Lift can be enabled with a Multi-Function Input (H01-01 ~ H01-08 = 44) under the
condition that all run commands have been removed and the drive is not outputting voltage.
When E-Lift is active, the drive will switch to the control method set in E03-01. In hoist applications, it
is highly recommended to leave E03-01 set to OLV, which will ensure the proper control of the load.
Furthermore, all functions that depend on encoder feedback will be disabled. The Test Mode
Configuration parameters (E03-xx group) are active during E-Lift operation instead of the E01-xx
parameters. By default, the E-Lift function may only remain operational for 10 minutes (user-
adjustable by C08-37), after which a fault will be generated.
E-Lift Setup Instructions
1.
Auto-Tune the motor:
Complete the Standard Tuning (Rotational Auto-Tuning) for the motor described in the Auto-Tun-
ing section beginning on page 4-17.
2.
Configure the E03 Parameter Group - Test Mode Configuration:
When E-Lift is active, the Test Mode parameters are utilized for voltage and frequency limits
instead of the E01 group. The E03 group should be configured as described Table 5-61.
WA R N I N G
During a BE5, BE6, or BE8 alarm, power should not be removed from the drive. The load
should be lowered to the ground and the crane moved to a safe location for service.
D A N G E R
E-Lift is designed to allow for temporary hoisting operations of motors normally equipped with
an encoder in Flux Vector control. Always follow instructions given in the E-Lift setup
instructions, and utilize extreme caution when operating a hoist in E-Lift mode. Stop the hoist if
any undesired motion occurs and contact Magnetek for additional assistance.
D A N G E R
Do NOT set E03-01 to a value of 0 (V/f Control) when using E-Lift in hoist applications. E-Lift is
designed to operate using the Open Loop Vector (OLV) control method. The use of the V/f
control method may cause undesired motion of the load and is only intended for
troubleshooting Flux Vector Control method related problems.
