Your example code is incomplete and doesn't run for me.

See this part of the documentation of colorbar (doc colorbar):
> Implementation Note: A colorbar is created as an additional axes object with the "tag" property set to "colorbar". The created object has the extra property "location" which controls the positioning of the colorbar.

So you could change the axes ticks like so:
hcb = colorbar();
set(hcb, "ytick", -250:50:250);  # <- set here where you want to show ticks on the colorbar
