ISP - Rev 6/95
1. Description
The ISP is an amplifier/power supply package, assembled on a single heatsink
with a Eurocard size. The rated output is up to 1500W.
The integrated power supply includes a shunt regulator.
The ISP is available in either panel version or rack version with a 32 poles
DIN 41612 connector.
Standard features
* Zero deadband.
* Excellent linearity.
* 2 inputs.
* Differential input.
* Motor current monitor.
* Inhibit/fault indication (free contact relay).
* Remote control functions: Inhibit and CW/CCW disable.
* Adjustable compensation.
* Adjustable continuous and peak current limits.
* Dynamic contouring of continuous and peak current limits.
* Input balance (offset) adjustment.
* Operation in two velocity modes (Tacho or armature voltage feedback) or current
mode.
* LEDs diagnostics.
* Option - Personality board for ease of replacement: the board includes all the

Protective functions:
The following protections cause an inhibit which is either self-restart or
latched (for manual reset) selectable by the user:
* Under / over voltage.
* Short circuit: between outputs or each output to ground.
* Low inductance.
* RMS current limit.
* Loss of tacho feedback.
* Over temperature.
* Duty cycle limit of the power supply's shunt regulator.
