HI/LO GAIN
SRC
(High / low gain change switch source)
This parameter determines the source of the
high / low gain switch.
The speed regulator high / low gain function was
developed in response to high performance
elevator requirements where the resonant
nature of the elevator system interferes with the
speed response of the drive.
For more information, see HI/LO GAIN SRC on
page 59.

SPEED REG
TYPE
(Speed Regulator Type)
This switch toggles between the Elevator Speed
Regulator (Ereg), the PI Speed Regulator,
external reg, and cemf reg. Magnetek
recommends the use of the Elevator Speed
Regulator for better elevator performance with
multi-step speed applications or when an active
torque Feed Forward signal is not available.
If set to CEMF REG, the drive will not use the
encoder as feedback, but rather the armature
voltage. Note: this is only meant for
maintenance. For more information, see
Armature Voltage Feedback on page 24.
If set to External Regulator, the drive will be
configured as a torque controller. The source of
the external torque command is determined by
the EXT TORQ CMD SRC (C1) parameter.
IMPORTANT: This assumes the car controller is
doing its own closed-loop speed regulation. (i.e.
a completely closed outer speed loop with the
car controller having its own encoder feedback).
The drive has the following three closed loop
speed regulation options and an option for
turning off the internal speed regulator:
• Elevator Speed Regulator (Ereg)
(see page 59)
• PI Speed Regulator (see page 60)
• External Speed Regulator

WARNING
If using an external speed regulator, which
produces an analog torque command to
Quattro (SPEED REG TYPE (C1) =
external reg and EXT TORQ CMD SRC
(C1) = analog input), it is imperative that the
encoder polarity matches the armature
voltage. To verify polarity, insert a torque
command into the analog input. Check
ENCODER SPD (D2) against ARMATURE
VOLTAGE (D2). Verify they are the same
polarity. If not, swap A and /A or change
the ENCODER CONNECT (C1) parameter.
