las nuevas versiones de cycle Analist tienen por omisión un start thrust y stop thrust que hay que afinar según el número de imanes del disco para que funcione; una vez hecho esto ya me funcionan dos de las 3 bicis. La otra no va nada, debe ser algo de hardware:
PAS->StrtThrsh and PAS->StopThrsh determine the pedal RPM at which the Cycle analyst detects that pedaling has started and stopped. In order for the CA to detect pedaling quickly on the first revolution and terminate assist power promptly after pedaling ceases, the start RPM is typically less than the stop RPM. PAS wheels with fewer magnets operate best with higher RPM settings.
Follow this procedure to configure these parameters:
1.Based on PASPoles, the CA provides default StartThrsh and StopThrsh values according to this table (may vary slightly). Use this table to restore default values if necessary.
2.StopThrsh should be set to the minimum RPM to yield an acceptable power cutoff delay when pedaling stops. Adjust as needed.
3.StartThrsh should be set to the maximum RPM to yield an acceptable power application delay when pedaling begins or resumes. Adjust as needed.
Note: Routine pedaling at RPMs between the StartThrsh and StopThrsh can cause power dropouts so the range should be minimized. Ideally this range is transitioned only when starting and stopping
De paso, he configurado el PAS como un custom torque en función del número de revoluciones, que funciona dando una potencia uniforme configurable hasta 55 rmp, y a partir de ahí modificando factor de escala:
6.5 AutoTorqPAS – AutoPAS with RPM-Proportional Assist
This techniques uses the TorqPAS setting with a simple PAS wheel to achieve rpm-proportional assist.
The Cycle Analyst has a pull-up on the Trq signal line so that with no torque sensor attached it receives a signal of approximately 5V which indicates the maximum crank torque. The default torque offset (voltage at which there is zero torque) is 2.5V which is correct for the Thun. From this the CA calculates (Trq Voltage) - (Trq->TrqOffst) ~=5V - 2.5V = 2.5V of normalized torque signal. The configured value of Trq->TrqScale is used to convert this toNm of torque, so for example, if Trq->TrqScale = +10 Nm/V, the result is 25Nm of torque. This 'apparent' torque is fixed and results only from the pull-up resistor and configured values. The CA uses this calculated torque and the RPM to figure out 'Human Watts', then multiplies that by Trq->AsstFactr get the assist in 'motor Watts'.
By choosing the proper Trq->TrqScale value and configuring the CA for TorqPAS, when pedaling is detected the CA will convert the fixed voltage (torque) from the pull-up resistor into Watts and apply it as assist - just like AutoPAS.
However, when doing Assist Watts calculations in TorqPAS mode, the CA assumes a baseline cadence of 55rpm. If the rider pedals faster than 55rpm, the assist wattage scales up with increasing cadence – exactly what we want.
Configured as described below, TorqPAS mode (with no torque sensor) will work like AutoPAS to give fixed assist up to 55rpm, then above that cadence it will give additional rpm-proportional assist.
The following two tables show the settings to achieve the Assist Watts (similar to PAS->PASWatts) at two different rpm levels: 55rpm (column 1) and 90rpm (other columns). The first column gives no power increase as cadence increases, while columns further to the right yield greater assist power as cadence increases. Each cell of the tables contain the target assist level in Watts at 90rpm and three values that must be transferred to Setup:
Begin by examining the stored Trq->TrqOffst voltage in Setup(see to right).
1.Use the first following table if you have the default Trq->TrqOffst of about 2.5V.For example, for 175W of assist @55rpm and 455W of assist @ 90rpm, locate the 175W row and the desired 455W column, then set:
2.A Trq->TrqOffst voltage close to 4.99V indicates that a Press-Hold operation has been done onTrq->TrqOffst which stored the pull-up voltage as the zero torque baseline. As a result, the pull-up resistor will now appear to be applying zero torque voltage so the resulting calculated torque will be zero. This situation can be remedied restoring the default 2.5V offset voltage using the Software Setup Utility or with a one-time calibration using a jumper plug to set the offset to 0.00V:To calibrate Trq->TrqScale = 0.00V: Make up a 5 pin JST that just jumps the Trq input (pin 5) to Gnd(pin 2), install this jumper plug on the CA Trq/PAS connector, and do the Press-Hold to set Trq->TrqOffst to 0.00V. Remove the jumper plug, and restore the regular PAS sensor connector. With this 0.00V calibration in place, use the second following table to select the appropriate settings as described for case (1).
