In the 5I25 G540 configuration a spare hardware stepgen is wired to and can used for the chargepump (just one pin). All Hostmot2 configurations have a watchdog so the stepgen will stop generating pulses in a few mS if the host hangs or crashes > > On 2013/01/22 11:25 AM, Chris Morley wrote: >> >> >>> From: [email protected] >>> Date: Mon, 21 Jan 2013 20:53:16 -0500 >>> To: [email protected] >>> Subject: [Emc-users] 5i25 and pncconf and g540 >>> >>> Can anyone tell me why it is so difficult to configure a G540 to run with a >>> 5i25? >>> >>> Chris Morley has done great work with pncconf.
