Parameter Description - Basic Set Up
The differential analog signals are connected to the terminals
X2A1(+) and X2A2(-) and X2A3(+) and X2A4(-). The actual torque
command is the sum of the differential inputs.
Torque command = (X2A1 - X2A2) + (X2A3 - X2A4).
In a torque controlled system the maximum speed is
controlled by the elevator control not the drive. However
for safety reasons the drive will internally limit the speed to
110% of LF.20 or contract speed.
Terminal X2A.14.5 is used to activate the starting and stopping
routine. The directions below must be followed in the exact
sequence they are listed:
Start: 1.) Enable X2A.16=on
2.) Select direction input X2A.14
3.) Drive commences current check and magnetizes
the motor when ready it will activate the DRO
output X2A.27...29.
4.) Controller gives analog torque signal
Stop: 1.) Analog signal => 0V
2.) Direction X2A.14 = off
3.) Enable X2A.16=off after the sum of the times
adjusted in LF.78 and LF.79.
c) Analog Torque control LF.02 = A tor
A Differential analog signal is connected to the terminals
X2A.1(+) and X2A.2 (-). Terminals X2A.3 and X2A.4 can be used
for pre-torque input.
0 ... ±10V = 0 ... ±max. system speed (LF.20)
Terminals X2A.14 and X2A.15 are used to activate the start and
stop routine. The directions below must be followed in the exact
sequence they are listed:
Start: 1.) Enable on X2A.16=on
2.) “Direction” input terminal (X2A.14 = on or
X2A.15 = on)
3.) Drive commences current check and magnetizes
the motor when ready it will activate the DRO
output X2A.27...29.
4.) Give analog speed signal
Stop: 1.) Analog signal => 0V
2.) Terminal X2A.14 / X2A.15 = off
3.) Enable X2A.16=off after the sum of the times
adjusted in LF.78 and LF.79.
d) Analog set speed selection LF.02 = A SPd
