The current gain of inputs 1 and 2 (current mode) is given by: 8 x Ic x Ki Gc = --------------- (A/V) 15 + Ri Ic - amplifier rated continuous current.
9 ISP - Rev 6/95 The current gain of the differential input in velocity mode is given by: 266 x Ic Gvd = ---------------- (A/V) R3 x R6 R3,R6 in Kohm The maximum input voltage at terminals 1 or 5 is calculated by: Vin max = 10 + 0.

11 ISP - Rev 6/95 4.4 Current loop Current loop control is obtained by op amp U1/B (Current amplifier) and R7, C2 which form a lag-lead network for current loop. The standard amp is equipped with R7 (100Kohm) and C2 (0.01 æ F) to get optimum current response for an average motor in this power range.
12 ISP - Rev 6/95 Ip - Iop Tp = 2.2ln ---------- Ip - Ic Ic - Amplifier continuous current rating. Ip - Peak demanded (not amplifier Ip) Iop - Actual operating current before the peak demand. Example: A motor is driven by an ISP-15/65 amplifier at constant speed and constant current of 5A.
13 ISP - Rev 6/95 4.6 Operation of the shunt regulator A shunt regulator is included in the power supply section of the ISP. The shunt regulator is a switching type, wherein dissipative elements (resistors) are switched across the DC bus, whenever the voltage reaches a predetermined level.
14 ISP - Rev 6/95 4.7 Protective functions All the protective functions (excluding 4.7.6) activate internal inhibit. There are two modes of resetting the amplifier after the cause of the inhibit disappears: Self Restart and Latch. - Self restart: The amplifier is inhibited only for the period that the inhibit cause is present.

For optimum dissipation the amplifier should be mounted with the fins vertical. 6.2 Wiring Proper wiring, grounding and shielding techniques are important in obtaining proper servo operation and performance.
27 ISP - Rev 6/95 6.3 Load inductance The total load inductance must be sufficient to keep the current ripple within the 50% limit (10-20% of rated current is recommended). The armature current ripple (Ir) can be calculated by using the following equation: 0.

36 ISP - Rev 6/95 7.1.2 Velocity mode To operate in velocity mode the velocity loop should be enabled by converting the error amplifier to a high gain PI amplifier. Make sure that: R6 (30ohm), R5 (475Kohm) and C1 (0.022 æ F), in solderless terminals, are installed on the board.
37 ISP - Rev 6/95 7.1.4 Activating the loss of tacho protection (velocity mode only) Activating the loss of tacho protection is done by installing R14 (different value for 65V or 135V amplifiers),R15,.
38 ISP - Rev 6/95 7.1.5 Latch mode of the protective functions Self Restart(D17 removed): The amplifier is inhibited only for the period that the inhibit cause is present. Latch (D17 - inserted): Failures 4.7.1-5 latch the Inhibit and the diagnostic LED.
39 ISP - Rev 6/95 7.3 Velocity control using armature voltage feedback The reference signal should be connected to the differential input and R3,R4 should be calculated and inserted according to: R3 = R4 = 1.33xVdm (Kohm) Vdm - maximum reference voltage at the differential input.
40 ISP - Rev 6/95 8. Amplifier adjustment and diagnostics Important remarks: A. If all the previous steps were accomplished you may now turn on the power and continue with the following adjustments. You may omit the step for current mode or velocity mode according to your application.
41 ISP - Rev 6/95 Ic Current monitor scale (A/V) : ------ 3.75 8.3 Adjusting the motor speed (velocity mode only) Adjusting the speed is done by adjusting the input gain trimmer of the tacho feedback: - Increasing/decreasing the feedback gain will decrease/increase the speed.
42 ISP - Rev 6/95 8.5 Response adjustment (velocity mode only) In most applications optimum response is achieved by adjusting the compensation (COMP) trimmer. Adjustment procedure is as follows: - Provide the amplifier with a low frequency, bi-directional square wave velocity command (A 0.
43 ISP - Rev 6/95 - If the previous step does not yield satisfactory results, if unacceptable overshooting has been noted, substitute a larger value than 0.022æF; or, if the response is overdamped substitute a smaller value than 0.022æF. Repetition of this procedure should yield an optimum choice for C1.
44 ISP - Rev 6/95 9. Tables and Summaries 9.1 Adjusting trimmers Six trimmers are installed on the ISP board with the following functions: T7 (Gain 1) - CW rotation increases input 1 gain. T6 (Gain 2) - CW rotation increases input 2 gain. T5 (Balance) - see 8.
45 ISP - Rev 6/95 Appendix A - Response adjustment - current loop In most applications it is not necessary to adjust the current loop to achieve the optimum response. When there are extreme electrical parameters in the armature circuit (inductance and resistance) the standard components values of 0.

47 ISP - Rev 6/95 Appendix B - Current limits contour adjustment The amplifier can be configured to have either continuous current limit or peak current limit or both which depend on motor velocity feedback. This function is enabled by calculating and inserting R11, R13.
48 ISP - Rev 6/95 Continuous current limit contouring: 1 - r1 R11 = 18.3 -------- (Kohm) 1 - r2 R11 R10 = 36.6 ------------- (Kohm) R11 + 20r1 Peak current limit contouring: 1 - s1 R13 = 18.
