TABLE 4-18 Resolver connection pins
Pin Name Description
1 +5L Not used
2 A+ Resolver Cos
3 A- Resolver Cos L
4 B+ Resolver Sin
5 B- Resolver Sin L
6 GND Not used
7 HA Not used
8 HB Not used
9 I+ Resolver reference
10 I- AGND (analog ground) for resolver reference
11 MTMPR A return for temperature sensor. (Internally connected to GND)
12 SCRN Screen (shield)
13 +5L Not used
14 HC Not used
15 MTMP Motor temperature input. A normally closed sensor must be
connected between MTMP pin 15 and pin 11. If no sensor is used,
pin 15 must be shorted to pin 11 for proper operation.
Control unit parameters:
• Reference signal from controller to resolver reference coil: sinusoidal wave, 4V±20% rms,
5kHz to 7kHz.
• Reference current (@5kHz): <25mA rms.
• Cos and Sin inputs to controller from resolver: 0V to 2V ±10% rms.
• Onboard resolver to digital converter (RDC): 12-bit resolution (4096 counts/rev), 1kHz
bandwidth.
Resolver parameters:
• Transformation ratio: 0.5.
• DC resistance: rotor >15Ω, stator >40Ω.
• Pole pairs: 1.
Resolver connection:
Cable for resolver connection must be shielded, twisted, triple pair, as shown in FIGURE 4-20.
