6.Installation procedures
6.1Mounting
The ISP series dissipates its heat by natural convection. For optimum dissipation the amplifier should be mounted with the fins vertical.
6.2Wiring
Proper wiring, grounding and shielding techniques are important in obtaining proper servo operation and performance. Incorrect wiring, grounding or shielding can cause erratic servo performance or even a
complete lack of operation.
a)Keep motor wires as far as possible from the signal level wiring (feedback signals, control signals, etc.).
b)If additional inductors (chokes) are required, keep the wires between the amplifier and the chokes as short as possible.
c)Minimize lead lengths as much as is practical.
d)Use twisted and shielded wires for connecting all signals (command and feedback). Avoid running these wires in close proximity to power leads or other sources of EMI noise.
e)Use a 4 wires twisted and shielded cable for the motor connection.
f)Shield must be connected at one end only to avoid ground loops.
g)All grounded components should be tied together at a single point (star connection). This point should then be tied with a single conductor to an earth ground point.
h)After wiring is completed, carefully inspect all conditions to ensure tightness, good solder joints etc.
A reliable connection with the spring type connectors is achieved with wires of 0.5mm 2
(AWG 20) stripped to a length of 11mm (.043").
