5. Loading: 20mA max each channel
6. Direction of rotation is controlled by slide switches: S25 and S29 as CW/OFF/CCW.
7. Clock source: Selectable from internal generators, control card’s pulse output (for PG-I only),
external source or PG-I (for PG-II only) through S26 and S30.
8. The ratio between input clock to output encoder frequency is 2:1.
9. Pulse per Revolution: Each encoder’s PPR can be set by S27 and S31 to values of 32, 64, 512,
1024, 2048, 4096 and 8192 PPR. One switch position at all times should be on only otherwise
the smallest ratio would become the PPR anyway.
• Load Emulator module:
1. Load Inductance range: Adjustable through S32 for most carrier frequencies
2. Inductance tuning: 0.1 to 0.99 for most carrier frequencies through VR6
3. Carrier frequency support: 400Hz-15kHz from the control card
4. Multi-level PWM: Two and three level topologies, and floating through S35.
5. Load current signal: Fully adjustable between 0-200% through VR7
6. IUVW (=IU+IV+IW) output for ground current measurements at J1 monitors. This signal is an
exact emulation to the one generated inside the control card for threshold testing purposes
7. PWM Monitoring: Twelve 2-level-phase-leg positioned LED’s for both 2 or 3 level fire-pulse
PWM signals, 2-levels are red and 1-levels are green, D1-D12.
8. Output signal access: Selectable through S22, S23, S24 (Internal/OFF/External)
9. PWM outputs loading: 0-10Vrms at 500 Ohms minimum load impedance
• Control I/O and External Access Port (EAP):
1. All the control-side analog inputs are selectable between internal and external sources at EAP
through S16.
2. All the control-side digital I/O’s are selectable between internal and external sources at EAP
through S13 to S18.
3. MCON and BTRA signals have Auto/Off/On modes through S19 and S20.
4. VCLL, VCHL, VCFL/SCL, FUL signals have High/Low/External modes through S13, S15,
S17 and S18.
5. Digital outputs routed to EAP, are all open collector/24V/40mA-max.
6. All the digital inputs are 5V-TTL except “MCOPL”, being 24V/2mA.
7. Analog inputs to the control card:
-“THM”: 0-5VDC (internally through VR10)
-“VDET: -10VDC-0VDC (internally through VR11)
-“CUV”: 3.3VDC-5VDC (internally through VR12)
• US_CODE module:
1. Selectable between internal HEX-rotary switch S36 and EAP through S14.
2. Format: 5V-TTL inputs from EAP, low-active/negative-logic.
• Test Points Connector J1:
1. Connector: Single-row header, .100” pitch, 40-pins
2. Loading: All short-circuit protected, measurement impedance 10kOhm-min. See Note 1.
3. Available Signals: All the signals at this connector are outputs except one, Pin 38, PGCKIN.
All the signals in detail are described in the next page table 1.
