SPD COMMAND SRC
(Speed Command Source)
This parameter designates the source of the
drive’s speed command.
The three possible sources for the speed
command are following:
•
Serial Channel - a RS-422 serial port located
on the drive control board (either speed
profile or multi-step speed commands)
= serial – speed profile
(only used in serial mode 1)
= ser mult step – serial multi-step speed
commands (only used in serial mode 2)
•
Analog Channel – a bipolar (
±
10V) signal.
Available with the analog channel is a Speed
Command Multiplier (SPD COMMAND
MULT(A1)) and Speed Command Bias (SPD
COMMAND BIAS(A1)). These parameters
are used to scale the user’s analog speed
command to the proper range for use by the
drive software.
•
Multi-Step Command - user defined fifteen
discrete speed commands (CMD1 - CMD15).
Four logic inputs are used as speed
command selections (CMD0 is reserved for
zero speed. But, the user can specify CMD1
- CMD15 to be any speed command either
positive or negative)
RUN COMMAND SRC
(Run Command Source)
This parameter allows the user to choose the
source of the run command from one of the
following sources: an external run signal from a
logic input (external tb1), a run signal transferred
across a serial channel (serial), or a signal from
both the serial channel and a logic input
(extrn). If a signal is required from a logic
input (either externaltb1 or extrn), the Run
signal on TB1 must be selected.
HI/LO GAIN SRC
(High / Low Gain 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.
When the speed response (gain) is set to high
levels, the resonant characteristics created by
the spring action of the elevator ropes can cause
car vibration. To solve this problem, the speed
regulator is set to a low enough response (gain)
so that the resonant characteristics of the ropes
are not excited.
This is accomplished by controlling the
sensitivity or response of the speed regulator via
the high / low gain switch and gain reduce
multiplier.
