2 Installation / Setup
2.1 Assembly, Installation
Assemble the servo amplifier as described in the product manuals for AX2000/2500. Observe
all safety instructions in the installation instructions that belong to the servo amplifier.
Follow all the notes on mounting position, ambient conditions, wiring, and fusing.
Only install and wire up the equipment in a de-energized condition, i.e. neither the
mains/line supply voltage nor the 24V auxiliary voltage nor the operating voltage of any
other connected equipment may be switched on. Take care that the control cabinet is safely
disconnected (lockout, warning signs etc.). The individual voltages are switched on for the
first time during setup.
Never disconnect the electrical connections to the servo amplifier while it is live. This could
destroy the electronics. Residual charges in the capacitors can still have dangerous levels
several minutes after switching off the supply power. Measure the voltage in the DC-link
circuit and wait until the voltage has fallen below 40V. Even when the motor is not running,
power and control cables can still be live.
2.1.1 Setting the station address and transmission rate
During setup it makes sense to use the keypad on the servo amplifier's front panel to preset the sta-
tion addresse and the Baud rate for communication (see setup instructions in the product manual).
Setting the station address
The station address can be set in three different ways:
l by using the pushbuttons on the front panel
(see installation instructions for AX2000/2500)
l In the setup software DRIVE.EXE, on the screen page “Basic settings”
l Using the ASCII command sequence: ADDR nn
Þ SAVE Þ COLDSTART (nn = address)
After changing the station address and/or baud rate you must turn the 24V auxiliary supply
for the servo amplifier off and on again for reset.
The address range can be expanded from 1 ... 63 to 1 ... 127 by using the ASCII-Object MDRV.
Setting the transmission rate
The CAN transmission rate can be set in three different ways:
l by using the pushbuttons on the front panel
(see product manual for AX2000/2500)
l In the setup software DRIVE.EXE, on the screen page “Basic settings”
l Using the ASCII command sequence: CBAUD bb
Þ SAVE Þ COLDSTART
(bb = transmission rate in kbit/s)
Possible transmission rates are: 20, 50, 100, 125, 250, 333, 500 (default), 666, 800, 1000 kbit/s.
