Magtrol Model DSP7000 Dynamometer Controller

Chapter 9 – Calibration

MAINTENANCE

 

6 = Io Card 2 Channel 1

 

7 = Io Card 2 Channel 2

6.  If the hard ware is not available the unit will respond “NoT INSTALLED.”  If the hardware 

is available the unit will respond “zERo To A/D#.”

7.  Apply +0.000 VDC and send the DSP7000 the zERoAD# command.  This command makes 

the DSP take a reading and save it as its offset value for that particular channel.  The unit 
will respond “FS To A/D#.”

8.  Apply approxi2.000 VDC for hD (# = 0 or 2) or approxi10.000 VDC for 

all others.

9.  Send the DSP7000 the FSAD#,xx.xxx command where xx.xxx represents the voltage applied.  

This command makes the DSP take a reading calculate the gain and save it as its gain value 
for that particular channel.

10.  The unit will respond “CAL CoMP AD#.”

 

NoTE: 

on units with Firmware Revisions Y0 and later a negative calibration 
can be performed for greater accuracy

11.  Apply approximately -2.000 VDC for hD (# = 0 or 2) or approximately -10.000 VDC for 

all others.

12.  Send the DSP7000 the FSAN#,xx.xxx command where xx.xxx represents the voltage applied.  

This command makes the DSP take a reading calculate the gain and save it as its gain value 
for that particular channel.

13.  The unit will respond “CAL CoMP AD#.”

Note: 

A calibration load of about 25 ohms (at least 50 watts) is required 
to calibrate the current outputs.

1.  D/A offset and gain on any of the 6 analog outputs.
 

•  TSC1 (Current and Voltage) Current from the brake connector, Voltage from the  

 

 

SUPPLY1 connector

 

•  TSC 2 (Current and Voltage) Current from the brake connector, Voltage from the  

 

 

SUPPLY2 connector

 

•  IO Card 1 Channel 1 (Commonly used as Analog Torque out)

 

•  IO Card 1 Channel 2 (Commonly used as Analog Speed out)

 

•  IO Card 2 Channel 1

 

•  IO Card 2 Channel 2

2.  If calibrating a Current output connect the voltmeter common bRAkE- connector (larger 

of the two pins).

3.  If calibrating a Voltage output connect the voltmeter common to output connector.
 

•  TSC1 = Pin 14 of the SUPPLY1 connector

 

•  TSC2 = Pin 14 of the SUPPLY2 connector
